[PATCH] net: ethtool: fix missing closing paren in rings_reply_size()

[Tao Cui]

sizeof(u32) on the _RINGS_CQE_SIZE line is missing its closing
parenthesis, causing nla_total_size() to absorb the subsequent
_TX_PUSH and _RX_PUSH entries. The resulting size estimate
happens to be numerically identical due to NLA alignment, but
the nesting is wrong and misleading.

Even thought the resulting size is identical, I am wondering if you
should add the Fixes: here. (or target net-next instead).

I think this is a net material, which will require a Fixes: tag.

Please always start a new thread for a new version of a
patch. Otherwise the CI/CD system just thinks it is a comment to an
existing patch.

For the record - no and no.
But don't repost this again, please, I'll clean up.
