[PATCH 6/7] ip1000: Add IPG_AC_FIFO flag when Tx reset

From: Jesse Huang <redacted>

This is a bug when Tx underrun happen, Tx reset without IPG_AC_FIFO will
cause Tx hold and can't transmit packet again.

Change Logs:
   1. Tx reset when Tx Under run will cause Tx fail
   2. ipg_nic_txcleanup() add "IPG_AC_FIFO" when Tx reset
