Subject: sh_eth: Implement multicast statistic based on the RFS8 status bit
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=25b77ad774a88cd7a9a8f63e122d4bda68479267;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

sh_eth: Implement multicast statistic based on the RFS8 status bit

At least on the R8A7790, RFS8 reflects the RINT8 (multicast) MAC
status flag.
