Subject: [PATCH 5.10 04/29] igb: Enable RSS for Intel I211 Ethernet Controller
Date: Wed,  5 May 2021 14:05:07 +0200	[thread overview]
Message-ID: <20210505112326.341867310@linuxfoundation.org> (raw)
In-Reply-To: <20210505112326.195493232@linuxfoundation.org>

From: Nick Lowe <nick.lowe@gmail.com>

commit 6e6026f2dd2005844fb35c3911e8083c09952c6c upstream.

The Intel I211 Ethernet Controller supports 2 Receive Side Scaling (RSS)
queues. It should not be excluded from having this feature enabled.

Via commit c883de9fd787 ("igb: rename igb define to be more generic")
E1000_MRQC_ENABLE_RSS_4Q was renamed to E1000_MRQC_ENABLE_RSS_MQ to
indicate that this is a generic bit flag to enable queues and not
a flag that is specific to devices that support 4 queues

The bit flag enables 2, 4 or 8 queues appropriately depending on the part.

Tested with a multicore CPU and frames were then distributed as expected.

This issue appears to have been introduced because of confusion caused
by the prior name.
