====================
net: Broadcom drivers sparse fixes

This patch series fixes the same warning reported by sparse in bcmsysport and
bcmgenet in the code that deals with inserting the TX checksum pointers:

drivers/net/ethernet/broadcom/bcmsysport.c:1155:26: warning: cast from restricted __be16
drivers/net/ethernet/broadcom/bcmsysport.c:1155:26: warning: incorrect type in argument 1 (different base types)
drivers/net/ethernet/broadcom/bcmsysport.c:1155:26:    expected unsigned short [unsigned] [usertype] val
drivers/net/ethernet/broadcom/bcmsysport.c:1155:26:    got restricted __be16 [usertype] protocol

This patch fixes both issues by using the same construct and not swapping
skb->protocol but instead the values we are checking against.
