net: dsa: tag_qca: fix wrong MGMT_DATA2 size
It was discovered that MGMT_DATA2 can contain up to 28 bytes of data instead of the 12 bytes written in the Documentation by accounting the limit of 16 bytes declared in Documentation subtracting the first 4 byte in the packet header. Update the define with the real world value. Tested-by: Ronald Wahl <ronald.wahl@raritan.com> Fixes: c2ee8181fddb ("net: dsa: tag_qca: add define for handling mgmt Ethernet packet") Signed-off-by: Christian Marangi <ansuelsmth@gmail.com> Cc: stable@vger.kernel.org # v5.18+ Signed-off-by: David S. Miller <davem@davemloft.net>
