Subject: RDMA/mlx5: Recover from fatal event in dual port mode
X-Git-Url: http://git.maquefel.me/?a=commitdiff_plain;h=97f30d324ce6645a4de4ffb71e4ae9b8ca36ff04;p=linux.git

RDMA/mlx5: Recover from fatal event in dual port mode

When there is fatal event on the slave port, the device is marked as not
active. We need to mark it as active again when the slave is recovered to
regain full functionality.

Fixes: d69a24e03659 ("IB/mlx5: Move IB event processing onto a workqueue")
