Subject: [PATCH net-next v2 08/12] net: stmmac: replace the multi_msi_en field with a flag

From: Bartosz Golaszewski <[email-masked]>
Date: Fri, 23 Jun 2023 12:08:41 +0200

From: Bartosz Golaszewski <[email-masked]>

Drop the boolean field of the plat_stmmacenet_data structure in favor of a
simple bitfield flag.
