3.2-stable review patch. If anyone has any objections, please let me know.
------------------ From: Dean Nelson <[email protected]> commit b868179c47e9e8eadcd04c1f3105998e528988a3 upstream. Commit d5bc77a223b0e9b9dfb002048d2b34a79e7d0b48 broke Wake-on-LAN by inadvertently dropping the enabling of DMA receives. Restore the enabling of DMA receives for WoL. This is applicable to 3.1+ stable trees.
