Subject: [PATCH net 1/2] net: stmmac: selftests: Update status when disabling RSS
Date: Fri, 10 Jan 2020 16:23:52 +0100	[thread overview]
Message-ID: <42050d75f00900b715a277bbc1d9abf437f6ea68.1578669661.git.Jose.Abreu@synopsys.com> (raw)
In-Reply-To: <cover.1578669661.git.Jose.Abreu@synopsys.com>
In-Reply-To: <cover.1578669661.git.Jose.Abreu@synopsys.com>

We are disabling RSS on HW but not updating the internal private status
to the 'disabled' state. This is needed for next tc commit that will
check if RSS is disabled before trying to apply filters.

Fixes: 4647e021193d ("net: stmmac: selftests: Add selftest for L3/L4 Filters")
