be2net: shorten AMAP_GET/SET_BITS() macro calls
The AMAP_GET/SET_BITS() macro calls take structure name as a parameter and hence are long and span more than one line. Replace these calls with a wrapper macros for RX/Tx compls and TX wrb. This results in fewer lines and more readable code in be_main.c Signed-off-by: Sathya Perla <sathya.perla@emulex.com> Signed-off-by: David S. Miller <davem@davemloft.net>
