When VLAN tagged frame is received the hardware sets 'LONG' bit of Rx status word. It is always set when the size of received frame exceeded 1518 bytes, including CRC. This VLAN tagged frame clears 'OK' bit of Rx status word such that driver should not rely on 'OK' bit of Rx status word to pass the VLAN tagged frame to upper stack. To fix the bug, don't use SIS_CMDSTS_PKT_OK for Rx error check and introduce SIS_RXSTAT_ERROR macro that checks Rx errors. If we are configured to accept VLAN tagged frames and the received frame size is less than or equal to maximum allowed length of VLAN tagged frame, clear 'LONG' bit of Rx status word before checking Rx errors.
