From: Sathya Perla Date: Tue, 2 Sep 2014 04:26:47 +0000 (+0530) Subject: be2net: shorten AMAP_GET/SET_BITS() macro calls X-Git-Url: https://git.karo-electronics.de/?a=commitdiff_plain;h=c3c18bc1de27741de9188094fcd4e253c9426164;p=linux-beck.git 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 Signed-off-by: David S.
