[PATCH net-next v3 12/12] net: stmmac: replace the en_tx_lpi_clockgating field with a flag

From: Bartosz Golaszewski
Date: Mon Jul 10 2023 - 05:01:38 EST


From: Bartosz Golaszewski <bartosz.golaszewski@xxxxxxxxxx>

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