Subject: [PATCH net-next v2 01/12] net: stmmac: replace the has_integrated_pcs field with a flag

From: Bartosz Golaszewski <[email-masked]>
Date: Fri, 23 Jun 2023 12:08:34 +0200

From: Bartosz Golaszewski <[email-masked]>

struct plat_stmmacenet_data contains several boolean fields that could be
easily replaced with a common integer 'flags' bitfield and bit defines.

Start the process with the has_integrated_pcs field.
