2015-11-25i40e: create a generic configure rss functionHelin Zhang3-52/+107
This patch renames the old pf-specific function in order to clarify its scope. This patch also creates a more generic configure RSS function with the old name. This patch also creates a new more generic function to get RSS configuration, using the appropriate method.

This patch fixes a problem where using ethtool rxnfc command could let RX flow hash be set on disabled queues.

2015-11-25i40evf: handle many MAC filters correctlyMitch Williams1-8/+24
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.

2015-11-25i40e: Move the saving of old link info from handle_link_event to link_eventCatherine Sullivan1-4/+3
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.

2015-11-24vrf: remove slave queue and private slave structNikolay Aleksandrov1-63/+5
The private slave queue and slave struct haven't been used for anything and aren't needed, this allows to reduce memory usage and simplify enslave/release. 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).

2015-11-23fm10k: Correct MTU for jumbo framesJacob Keller1-1/+1
Based on hardware testing, the host interface supports up to 15368 bytes as the maximum frame size. To determine the correct MTU, we subtract 8 for the internal switch tag, 14 for the L2 header, and 4 for the appended FCS header, resulting in 15342 bytes of payload for our maximum MTU on jumbo frames.
