This patch fixes a problem where using ethtool rxnfc command could let RX flow hash be set on disabled queues. This patch fixes the problem by returning the number of enabled queues before setting rxnfc. Change-ID: Idbac86b0b47ddacc8deee7cd257e41de01cbe5c0 Signed-off-by:

When a lot (many hundreds) of MAC or VLAN filters are added at one time, we can overflow the Admin Queue buffer size with all the requests. Unfortunately, the driver would then calculate the message size incorrectly, causing it to be rejected by the PF. Furthermore, there was no mechanism to trigger another request to allow for configuring the rest of the filters that didn't fit into the first request. To fix this, recalculate the correct buffer size when we detect the overflow condition instead of just assuming the max buffer size. Also, don't clear the request bit in adapter->aq_required when we have an overflow, so that the rest of the filters can be processed later.

The watchdog only calls link_event not handle_link_event which means that we need to save the old information in link_event. Previously when polling we were comparing current data to the old data saved the last time we actually received a link event. This means that the polling would only fix link status changes in one direction depending on what the last old data saved off was. Change-ID: Ie590f30fdbcb133d0ddad4e07e3eb1aad58255b3 Signed-off-by:

We can use netdev_for_each_lower_dev() to free the vrf ports when deleting a vrf device. Also if in the future a private struct is needed for each slave, it can be implemented via lower devices' private member (similar to how bonding does it). Signed-off-by:

Commit 09605cc1 ("net ipv4: use preferred log methods") replaced a few calls of pr_cont() after a console print without a trailing newline by pr_info(), causing lines to be split during IP autoconfiguration, like: . , OK IP-Config: Got DHCP answer from 192.168.97.254, my address is 192.168.97.44 Convert these back to using pr_cont(), so it prints again: ., OK IP-Config: Got DHCP answer from 192.168.97.254, my address is 192.168.97.44 Absorb the printing of "my address ..." into the previous call to pr_info(), as there's no reason to use a continuation there.

This adds an explicit #include statement to make it compile in all configurations. The reset functionality will not work without gpiolib, which is what you get when disabling the feature. As far as I can tell, gpiolib is supported on all architectures on which you can have DSA at the moment. Signed-off-by:

Jeff Kirsher says: ==================== Intel Wired LAN Driver Updates 2015-11-23 This series contains updates to ixgbe, ixgbevf, fm10k, i40e and i40evf. Jacob fixes an issue where VF could attempt to read queues it does not own, so prevent this we check queue 0 before we continue. Matthew fixes the MTU for jumbo frames for fm10k. Julia Lawall cleans up a unneeded NULL test in ixgbe. Mark cleans up a redundant header inclusion. Adds KR mode support for CS4227 chip. Cleaned up diagnostic code, which is no longer needed, for the CS4227 chip. Jean Sacren fixes kernel documentation for ixgbe. Alex Duyck fixes an fm10k and ixgbe issue in which the polling routine would increase the budget for receive to at least 1 per queue if multiple queues were present. This would result in receive packets being processed when the budget was 0 which is meant to indicate that no receive can be handled. Also fixes an ixgbevf performance issue where netperf test will starve for memory in the time form one transmit interrupt to the next, so limit lowest interrupt rate for adaptive interrupt moderation to 12K. Fixed up ixgbe and ixgbevf to use napi_schedule_irqoff() where the drivers were run from hard interrupt context or with interrupts already disabled in netpoll. Jesse fixes a compiler warning about an unused variable for i40evf. John Greene fixes an issue with ixgbevf, where if the VF driver is loaded while the corresponding PH interface is down, the driver assigns a random MAC address, can be overwritten with the value of hw->mac.perm_addr which is 0 at that point. So avoid this case by initializing hw->mac.perm_addr to the randomly generated address and do not set it unless we receive an ACK from ixgbe.
