Subject: [PATCH 5.10 252/530] crypto: chelsio - Read rxchannel-id from firmware
From: Ayush Sawal <ayush.sawal@...lsio.com>
[ Upstream commit 16a9874fe468855e8ddd72883ca903f706d0a9d0 ]
The rxchannel id is updated by the driver using the
port no value, but this does not ensure that the value
is correct. So now rx channel value is obtained from
etoc channel map value.
Fixes: 567be3a5d227 ("crypto: chelsio - Use multiple txq/rxq per...")
