X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=4ee9130f64238677cdff5948812426c1c75c0c5f;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

net: mvneta: fix enable of all initialized RXQs

[ Upstream commit e81b5e01c14add8395dfba7130f8829206bb507d ]

In mvneta_port_up() we enable relevant RX and TX port queues by write
queues bit map to an appropriate register.

q_map must be ZERO in the beginning of this process.
