[TG3]: Fix bug in setting a tg3_flag
Found a bug while reviewing the patches the second time. The TG3_FLAG_TXD_MBOX_HWBUG flag is set after the register access methods have been determined. This patch fixes it by moving it up before the various access methods are assigned. Signed-off-by: Michael Chan <mchan@broadcom.com> Signed-off-by: David S. Miller <davem@davemloft.net>
