ar71xx: fix up alignment handling
- on ar724x, rx buffers can be aligned with an offset of 2, which keeps the ip header aligned - alignment offset is only added if the ar8216 workaround is not active and the phy driver does not advertise its own packet alignment - ar71xx and ar91xx can not handle rx alignment offsets, however taking a hit on unaligned exceptions seems to have less overhead than re-aligning the data for large packets - use memmove to re-align small packets, if necessary tested on ar9132, ar7240 and ar7242 based devices without ar8216 headers git-svn-id: svn://svn.openwrt.org/openwrt/trunk@20892 3c298f89-4303-0410-b956-a3cf2f4a3e73
