This patch series contain the below fixes. - Infinite loop error when tx credits becomes 0. - Race condition between tx skb reference pointers. v2: - Added mutex lock to protect tx skb reference handling. v3: - Added mutex protection in assigning new tx skb to waiting_tx_skb pointer. - Explained the possible scenario for the race condition with the time diagram in the commit message. v4: - Replaced mutex with spin_lock_bh() variants as the start_xmit runs in BH/softirq context which can't take sleeping locks.
