Don't do the weird indenting.

It would be better to fix this like so:

	memcpy(pDevice->sTxEthHeader.abyDstAddr, pbySkbData, ETH_HLEN);

Remove the silly cast here as well.

				pDevice->wCurrentRate = pDevice->uConnectionRate;

Both your patch and mine are still 81 characters long.

I don't get upset by lines over 80 characters...  Eventually we will fix
