Subject[PATCH 5.10 063/105] iavf: Fix missing check for running netdev
Date
From: Slawomir Laba <slawomirx.laba@intel.com>

commit d2c0f45fcceb0995f208c441d9c9a453623f9ccf upstream.

The driver was queueing reset_task regardless of the netdev
state.

Do not queue the reset task in iavf_change_mtu if netdev
is not running.

Fixes: fdd4044ffdc8 ("iavf: Remove timer for work triggering, use delaying work instead")
