Subject: Fix ethernet multicast for ucc_geth.
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=9030b3dd671d672f5fcc91c2ec48f02082310af4;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

Fix ethernet multicast for ucc_geth.

hw_add_addr_in_hash() already swaps byte
order, don't do it in ucc_geth_set_multi() too.
