Move PSTxDesc->m_td1TD1 to inside spin locks. if m_td1TD1.byTCR has TCR_EDP and TCR_STP are set, the interrupt handler will try and complete the buffer before it is completed. Usually on the tail of a burst of tx packets. This results in a partially completed packet being transmitted or worse sitll dead lock when skb is freed by the interrupt handler. Set head_td->m_td1TD1.byTCR to 0 in first lock of vnt_tx_packet to stop interrupt handler completing the buffer. Move Set TSR1 & ReqCount in s_cbFillTxBufHead to the second lock. cbReqCount is carried to the second lock in pTDInfo->dwReqCount without the padding removed. Signed-off-by:
