Subject: net: hns3: fix bug when calculating the TCAM table info
From: Jian Shen <shenjian15@xxxxxxxxxx>
commit b36fc875bcdee56865c444a2cdae17d354a6d5f5 upstream.
The function hclge_fd_convert_tuple() is used to convert tuples
and tuples mask to TCAM x and y. But it misuses the source mac
as source mac mask when convert INNER_SRC_MAC, which may cause
the flow director rule works unexpectedly. So fix it.
Fixes: 117328680288 ("net: hns3: Add input key and action config support for flow director")
