IOW, MAC Merge TX can be enabled with or without verification, but verification with TX disabled makes no sense. The pmac-enabled boolean (ETHTOOL_A_MM_PMAC_ENABLED) was intended to be a global toggle from an API perspective, whereas tx-enabled just handles the TX direction. IOW, the pMAC can be enabled with or without TX, but it doesn't make sense to enable TX if the pMAC is not enabled. Add two checks which sanitize and reject these invalid cases.
