40GbE Intel Wired LAN Driver Updates 2017-10-02
This series contains updates to i40e and i40evf.
Shannon Nelson fixes an issue where when a machine has more CPUs than
queue pairs, the counting gets a "little funky" and turns off Flow
Director. So to correct it, limit the number of LAN queues initially
allocated to be sure there are some left for Flow Director and other
features.
Lihong cleans up dead code by removing a condition check which cannot
ever be true.
Christophe Jaillet fixes a potential NULL pointer dereference, which
could happen if kzalloc() fails.
Filip corrects the reporting of supported link modes, which was incorrect
for some NICs. Added support for 'ethtool -m' command, which displays
information about QSFP+ modules.
Mariusz adds functions to read/write the LED registers to control the
LEDS, instead of accessing the registers directly whenever the LEDs
need to be controlled.
Jake fixes a regression where we introduced a scheduling while atomic,
so introduce a separate helper function which will manage its own need
for the mac_filter_hash_lock. Also cleaned up the "PF" parameter in
i40e_vc_disable_vf() since it is never used and is not needed. Fixed
a rare case where it is possible that a reset does not occur when
i40e_vc_disable_vf() is called, so modify i40e_reset_vf() to return a
bool to indicate whether it reset or not so that i40e_vc_disable_vf()
can wait until a reset actually occurs.
Alan adds the ability for the VF to request more or less underlying
allocated queues from the PF. Fixes the incorrect method for clearing
the vf_states variable with a NULL assignment, when we should be
using atomic bitops since we don't actually want to clear all the
flags. Fixed a resource leak, where the PF driver fails to inform
clients of a VF reset because we were incorrectly checking the
I40E_VF_STATE_PRE_ENABLE bit.
Mitch converts i40evf_map_rings_to_vectors() to a void function since
it cannot fail and allows us to clean up the checks for the function
return value.
Scott enables the driver(s) to pass traffic with VLAN tags using the
802.1ad Ethernet protocol.
