Vladimir Oltean 9f5548e421 net: dsa: tag_sja1105: fix MAC DA patching from meta frames
[ Upstream commit 1dcf6efd5f0c1f4496b3ef7ec5a7db104a53b38c ]

The SJA1105 manual says that at offset 4 into the meta frame payload we
have "MAC destination byte 2" and at offset 5 we have "MAC destination
byte 1". These are counted from the LSB, so byte 1 is h_dest[ETH_HLEN-2]
aka h_dest[4] and byte 2 is h_dest[ETH_HLEN-3] aka h_dest[3].

The sja1105_meta_unpack() function decodes these the other way around,
so a frame with MAC DA 01:80:c2:11:22:33 is received by the network
stack as having 01:80:c2:22:11:33.
