I read through the Intel datasheet of the 82599 ethernet adapter and would like to test the mentioned filters. I used the 'ethtool -U [interface]' at the beginning but I can't find any flow-types for IPv6 headers, so my question is it possible to enable all mentioned filters in the datasheet with the 'ethtool'? Is there maybe any documentation with examples in it?

I have a machine (SuperMicro H8SCM, AMD Opteron) with an I340-T4 PCIe NIC connected. I'm running CentOS 6.2 with the latest updated kernel. There's a single cable connecting the first port on the card to a switch. When the machine POST's, the link light is on. Even at the GRUB menu, the link light is still on. However, as soon as the kernel begins to load, the link light disappears until I reboot. Even rmmod'ing the driver won't bring it back. At first I thought it was a hardware problem. So I swapped it out with the other one I had. (I bought two.) Same issue. Then I tried a Fedora 16 live CD. And everything "just worked." FWIW, Ubuntu 10.04.4 has the same issue when I tested it. So at this point, I know my hardware and network configuration are good. What I can't figure out, is why the igb driver initializes perfectly, but the link light never turns on? I managed to get the link light up in CentOS ONCE and ONLY once, via some combination of rmmod/modprobe WRT the igb and e1000e driver. This motherboard also has two Intel 82574L onboard using e1000e. Sadly, I can't disable them in the BIOS, as far as I can tell. I reached out to #centos on freenode after struggling for weeks on my own with this problem. no resolution was forthcoming. I've also tried the following things, and they produced no results: 1) blacklisting the e1000e module and running just igb. 2) using IntMode=0,0,0,0 for igb 3) statically assigning aliases in modprobe.conf 4) Upgrading to the latest e1000e and igb drivers using elrepo.org RPM's. There are more items, but they were all basic variants of the above. At any rate, I was wondering if anyone here had any insight into the matter? Thanks, - -- Nick -----BEGIN PGP SIGNATURE----- Version: GnuPG v2.0.18 (GNU/Linux) Comment: Using GnuPG with Mozilla - http://enigmail.mozdev.org/ iEYEARECAAYFAk+/7c8ACgkQdD1FRJKImAP8DACffj5FkYR6W0J431BLtF4IF5uH 67UAn2yVizxsmDVBXhrnFT1j8QRMSGfX =Sg2D -----END PGP SIGNATURE----- ------------------------------------------------------------------------------ Live Security Virtual Conference Exclusive live event will cover all the ways today's security and threat landscape has changed and how IT managers can respond.

I'm currently working on an ixgbevf driver. Due to some special requirements, I need to pre-allocate a pool of contiguous RX and TX buffer (4MB total in my case). I chopped the pool into multiple pages and assigned one-by-one to the RX and TX ring buffer. I also implemented a bitmap to manage the free/allocation of this DMA pool. When packet is coming, the ixgbevf device DMA the packet into the RX buffer. Then my modified version of ixgbevf driver needs to do an "skb_copy" to copy the whole packet out of the pre-allocated pool so that the Linux kernel later on can free this copied skb and the buffer in the pre-allocated pool can be freed. Same ideal in the case of transmission. Everything works fine until I found a poor reception performance. I got TX: 9.4Gbps and RX: 1Gbps. I looked into the problem and found my driver spent quite a long time in doing 1. skb_copy in ixgbevf_clean_rx_irq and 2. netdev_alloc_skb_ip_align (in ixgbevf_alloc_rx_buffers). Compared with original ixgbevf code, I found most of the drivers are using dma_map_single/dma_unmap_single, which is streaming DMA mappings. However, I'm using coherent DMA mapping (dma_alloc_coherent) to allocate a big DMA buffer and assigning each piece to the RX ring. I'm wondering the performance impact of using dma_alloc_coherent, and is it possible that my poor performance is caused by this? Thanks a lot!

We are seeing a non-zero value of 65355 being returned for speed_hi for the ethtool_cmd structure for the ioctl ETHTOOL_GSET. when the interface is up it returns zero for speed_hi. For setting the Ethernet speed/duplex we first query the driver with the ioctl ETHTOOL_GSET and change only the speed and duplex values in the ethtool_cmd structure and leave the rest(speed_hi) as is and invoke the ioctl ETHTOOL_SSET. We don't see this issue with the older driver version - 1.0.2-k2 . I have looked at the function e1000_get_settings in the newer driver version, where the following code seems to cause the problem. speed = -1; ecmd-&gt;duplex = -1; if (netif_running(netdev)) { if (netif_carrier_ok(netdev)) { speed = adapter-&gt;link_speed; ecmd-&gt;duplex = adapter-&gt;link_duplex - 1; } } else { u32 status = er32(STATUS); if (status &amp; E1000_STATUS_LU) { if (status &amp; E1000_STATUS_SPEED_1000) speed = SPEED_1000; else if (status &amp; E1000_STATUS_SPEED_100) speed = SPEED_100; else speed = SPEED_10; if (status &amp; E1000_STATUS_FD) ecmd-&gt;duplex = DUPLEX_FULL; else ecmd-&gt;duplex = DUPLEX_HALF; } } ethtool_cmd_speed_set(ecmd, speed); In the above code fragment speed is defined as u32 and set to -1 which means 4294967295. When the control doesn't enter the either of above if-else branch. speed will be 4294967295. So when ethtool_cmd_speed_set() gets called, speed and hi_speed both gets set to 65535. In the driver version 1.0.2-k2, the code is different and ethtool_cmd_speed_set() is not used to set the speed values. Can you please let me know if this behavior is right and if not should I raise a bug to get it fixed.

The crash is not very reproducible we can only see it a few times right after the machines were rebooted. If we were to run the machine in a warm state, we don't likely see this problem. I wonder if you have heard the similar report like this? There are two ways we are thinking of fixing this bug. First approach --------------- Please note that ixgbe_clean_rx_irq_bb() has a different way to deal with this problem. It checks if skb is NULL, if it is, it would try to the skb from the recycle q, if fails, it will call netdev_alloc_skb_ip_align() to get a skb. Would you suggest the following code (NULL_POINTER_FIX) is a proper way to fix this problem. while (ixgbe_test_staterr(rx_desc, IXGBE_RXD_STAT_DD)) { union ixgbe_adv_rx_desc *next_rxd; struct ixgbe_rx_buffer *rx_buffer_info; struct sk_buff *skb; bool pkt_is_rsc; rx_buffer_info = &amp;rx_ring-&gt;rx_buffer_info[i]; skb = rx_buffer_info-&gt;skb; rx_buffer_info-&gt;skb = NULL; /* * This memory barrier is needed to keep us from reading * any other fields out of the rx_desc until we know the * RXD_STAT_DD bit is set */ rmb(); pkt_is_rsc = ixgbe_get_rsc_state(rx_ring, rx_desc); #define NULL_POINTER_FIX #ifdef NULL_POINTER_FIX if (!skb) { printk("%s:%d no skb\n", __FUNCTION__, __LINE__); #ifndef IXGBE_NO_LRO /* retreive any recycled skbs first before allocating */ skb = ixgbe_lro_recycled_skb(q_vector); if (!skb) #endif skb = netdev_alloc_skb_ip_align(netdev_ring(rx_ring), IXGBE_RX_HDR_SIZE); if (!skb) { printk("%s:%d cannot alloc skb\n", __FUNCTION__, __LINE__); rx_ring-&gt;rx_stats.alloc_rx_buff_failed++; break; } /* * Delay unmapping of the first packet. It carries the * header information, HW may still access the header * after the writeback. Only unmap it when EOP is * reached */ IXGBE_CB(skb)-&gt;dma = rx_buffer_info-&gt;page_dma; /* initialize skb for ring */ skb_record_rx_queue(skb, ring_queue_index(rx_ring)); } #endif // NULL_POINTER_FIX Second Approach --------------------- Another approach we have in mind is to force ixgbe_alloc_rx_buffer_ps() to be called whenever the recycle queue is empty. while (ixgbe_test_staterr(rx_desc, IXGBE_RXD_STAT_DD)) { ... bool pkt_is_rsc, force_alloc = false; // added force_alloc ... #ifndef IXGBE_NO_LRO if (ixgbe_can_lro(rx_ring, rx_desc, skb)) { // force allocation whenever the recycle q is empty ixgbe_lro_receive(q_vector, skb); rx_buffer_info-&gt;skb = ixgbe_lro_recycled_skb(q_vector); if (rx_buffer_info-&gt;skb == NULL) { rx_buffer_info-&gt;dma = 0; /* XXX */ printk(KERN_CRIT "%s: forcing allocation\n", __func__); force_alloc = true; } ... /* return some buffers to hardware, one at a time is too slow */ // when force_alloc is true, we would get more skb if (force_alloc || cleaned_count &gt;= IXGBE_RX_BUFFER_WRITE) { ixgbe_alloc_rx_buffers_ps(rx_ring, cleaned_count); cleaned_count = 0; } ... } This is crash is tough to reproduce so it is very hard to test again either one of the proposed fix above. Would you please kindly make any suggestion to the fix of this problem?

The box is using Oracle Linux 6 (RHEL6 clone) however it is using the "unbreakable enterprise kernel" 2.6.39-100.6.1.el6uek.x86_64 which is based on mainline Linux 3.0.16 with some patches. The public git repo for the kernel is here: http://oss.oracle.com/git/?p=linux-uek-2.6.39.git;a=summary With the latest igb-3.4.7 driver I have don't have link after a reboot. I have to unload and reload the driver to get link. modprobe -r igb sleep 2 modprobe igb Note, I did have to apply this patch to kcompat.h to get it to compile: #if ( LINUX_VERSION_CODE &lt; KERNEL_VERSION(3,3,0) ) -typedef u32 netdev_features_t; +/* typedef u32 netdev_features_t; */ UPDATE: I found out that I lost link when the Dell OMSA daemons start.
