Doc: hisi: hns adds mc-mac-mask property
Since there is not enough tcam table entries for every vlan and multicast address, HNS needs to add support of fuzzy matching of TCAM tables. Adding the property to mask the bits to be fuzzy matched, so update the bindings document Signed-off-by: Kejian Yan <yankejian@huawei.com> Reviewed-by: Yisen Zhuang <yisen.zhuang@huawei.com> Signed-off-by: Salil Mehta <salil.mehta@huawei.com> Signed-off-by: David S.
