mgmt Ethernet packet can read/write up to 16byte at times. The len reg is limited to 15 (0xf). The switch actually sends and accepts data in 4 different steps of len values. Len steps: - 0: nothing - 1-4: first 4 byte - 5-6: first 12 byte - 7-15: all 16 byte In the alloc skb function we check if the len is 16 and we fix it to a len of 15. It the read/write function interest to extract the real asked data. The tagger handler will always copy the fully 16byte with a READ command. This is useful for some big regs like the fdb reg that are more than 4byte of data. This permits to introduce a bulk function that will send and request the entire entry in one go. Write function is changed and it does now require to pass the pointer to val to also handle array val. Signed-off-by:
