Subject: [PATCH 8/9] net/gve: don't reset ring size bounds to default on reset
Date: Wed,  1 Jul 2026 11:35:26 -0700	[thread overview]
Message-ID: <20260701183528.2443032-9-joshwash@google.com> (raw)
In-Reply-To: <20260701183528.2443032-1-joshwash@google.com>

On device reset, GVE skips describe_device functionality, as the device
is not expected to change on a reset. However, before skipping the
describe_device functionality, GVE still sets the ring sizes to their
default values. This effectively removes the ability to create queues
with higher-than-default descriptor counts after a reset.

Fix this behavior by only setting the default ring size bounds is
describe_device is being executed.

Fixes: 1bf64edce3c4 ("net/gve: add reset path")
