Subject: [PATCH v2 net-next 7/8] ionic: change set_rx_mode from_ndo to can_sleep
Date: Thu,  5 Nov 2020 16:12:19 -0800	[thread overview]
Message-ID: <20201106001220.68130-8-snelson@pensando.io> (raw)
In-Reply-To: <20201106001220.68130-1-snelson@pensando.io>

Instead of having two different ways of expressing the same
sleepability concept, using opposite logic, we can rework the
from_ndo to can_sleep for a more consistent usage.

Fixes: 1800eee16676 ("net: ionic: Replace in_interrupt() usage.")
