It's still really weird looking though.
There are several of these in the intel drivers too: drivers/net/ethernet/intel/e1000/e1000_ethtool.c: memset(&skb->data[frame_size / 2 + 10], 0xBE, 1); drivers/net/ethernet/intel/e1000/e1000_ethtool.c: memset(&skb->data[frame_size / 2 + 12], 0xAF, 1); drivers/net/ethernet/intel/e1000e/ethtool.c: memset(&skb->data[frame_size / 2 + 10], 0xBE, 1); drivers/net/ethernet/intel/e1000e/ethtool.c: memset(&skb->data[frame_size / 2 + 12], 0xAF, 1); drivers/net/ethernet/intel/igb/igb_ethtool.c: memset(&skb->data[frame_size + 10], 0xBE, 1); drivers/net/ethernet/intel/igb/igb_ethtool.c: memset(&skb->data[frame_size + 12], 0xAF, 1); drivers/net/ethernet/intel/ixgbe/ixgbe_ethtool.c: memset(&skb->data[frame_size + 10], 0xBE, 1); drivers/net/ethernet/intel/ixgbe/ixgbe_ethtool.c: memset(&skb->data[frame_size + 12], 0xAF, 1); drivers/staging/qlge/qlge_ethtool.c: memset(&skb->data[frame_size / 2 + 10], 0xBE, 1); drivers/staging/qlge/qlge_ethtool.c: memset(&skb->data[frame_size / 2 + 12], 0xAF, 1); _______________________________________________ devel mailing list de...@linuxdriverproject.org http://driverdev.linuxdriverproject.org/mailman/listinfo/driverdev-devel
