Subject: [PATCH net-next RFC 0/3] Add mlx5 devices FW upgrade reset support
Date:   Tue, 14 Jan 2020 17:55:25 +0200

This patchset adds support for FW upgrade.
On devlink reload, if a pending FW image is found, the driver will perform
a FW upgrade reset flow to activate the pending FW image.

Sending as RFC because the FW activation reset requires a pci link
toggling. Although it works and we verify that the device is the only
device on the pcie bridge before allowing such reset, as already done by
other drivers [1], we would like to get some feedback on the last patch
of this series.

[1] function trigger_sbr() at drivers/infiniband/hw/hfi1/pcie.c
