Subject: [PATCH 1/3] common/sfc_efx/base: fix assignment of maximum Tx data count
Date: Fri, 12 Aug 2022 15:24:52 +0300	[thread overview]
Message-ID: <20220812122454.1947322-1-ivan.malov@oktetlabs.ru> (raw)

Maximum data count of a Tx descriptor is advertised to users,
however, this value is mistakenly derived from the Rx define.
Use the Tx one instead. The resulting value will be the same.

Fixes: 1e43fe3cb41e ("net/sfc/base: separate limitations on Tx DMA descriptors")
Cc: stable@dpdk.org
