Subject: [PATCH net-next 1/1] net: stmmac: perserve TX and RX coalesce value during XDP setup
Date: Wed, 24 Nov 2021 19:40:19 +0800	[thread overview]
Message-ID: <20211124114019.3949125-1-boon.leong.ong@intel.com> (raw)

When XDP program is loaded, it is desirable that the previous TX and RX
coalesce values are not re-inited to its default value. This prevents
unnecessary re-configurig the coalesce values that were working fine
before.

Fixes: ac746c8520d9 ("net: stmmac: enhance XDP ZC driver level switching performance")
