Subject: [PATCH net-next v3 05/12] net: stmmac: replace the tso_en field with a flag
From: Bartosz Golaszewski <bartosz.golaszewski@...aro.org>
Drop the boolean field of the plat_stmmacenet_data structure in favor of a
simple bitfield flag.
Signed-off-by: Bartosz Golaszewski <bartosz.golaszewski@...aro.org>
