From f109603a4be0578a8145c8ae7d6e10b0b5ab6df4 Mon Sep 17 00:00:00 2001 From: Brett Creeley Date: Fri, 15 May 2020 17:51:17 -0700 Subject: ice: allow host to clear administratively set VF MAC Currently a user is not allowed to clear a VF's administratively set MAC on the PF. Fix this by allowing an all zero MAC address via "ip link set ${pf_eth} vf ${vf_id} mac 00:00:00:00:00:00". An example use case for this would be issuing a "virsh shutdown" command on a VM. The call to iproute mentioned above is part of this flow. Without this change the driver incorrectly rejects clearing the VF's administratively set MAC and prints unhelpful log messages. Also, improve the comments surrounding this change.

This is a required step in VF driver load. Currently, the PF is only allowing a VF to request reset using this method after the VF has already communicated resources via VIRTCHNL_OP_GET_VF_RESOURCES. However, this is incorrect because the VF can request reset before requesting resources. Fix this by allowing the VF to request a reset once it has been initialized.

However, when the number of q_vectors are increased the settings for the new q_vectors will be set to the driver defaults of AIM on, Rx/Tx ITR 50, and INTRL 0. This is causing issues with how the ethtool layer gets the current coalesce settings since it only uses q_vector 0. So, assume that the user set the coalesce settings globally (i.e. ethtool -C eth0) and use q_vector 0's settings for all of the new q_vectors.
