Merge branch '1GbE' of git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/net-queue
Jeff Kirsher says: ==================== Intel Wired LAN Driver Updates 2018-04-24 This series contains fixes to ixgbevf, igb and ice drivers. Colin Ian King fixes the return value on error for the new XDP support that went into ixgbevf for 4.17. Vinicius provides a fix for queue 0 for igb, which was not receiving all the credits it needed when QAV mode was enabled. Anirudh provides several fixes for the new ice driver, starting with properly initializing num_nodes_added to zero. Fixed up a code comment to better reflect what is really going on in the code. Fixed how to detect if an OICR interrupt has occurred to a more reliable method. Md Fahad fixes the ice driver to allocate the right amount of memory when reading and storing the devices MAC addresses. The device can have up to 2 MAC addresses (LAN and WoL), while WoL is currently not supported, we need to ensure it can be properly handled when support is added. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
