Subject: [PATCH net-next 11/14] bnxt_en: Reserve rings in bnxt_set_channels() if device is down.
Date: Wed, 25 Apr 2018 20:40:54 -0400	[thread overview]
Message-ID: <1524703257-12812-12-git-send-email-michael.chan@broadcom.com> (raw)
In-Reply-To: <1524703257-12812-1-git-send-email-michael.chan@broadcom.com>

The current code does not reserve rings during ethtool -L when the device
is down.  The rings will be reserved when the device is later opened.

Change it to reserve rings during ethtool -L when the device is down.
This provides a better guarantee that the device open will be successful
when the rings are reserved ahead of time.
