As we sometime run into TX timeout from IPoIB, queue seems stopped and can't recover. Diff with Mellanox OFED show Mellanox driver has timeout work to recover in such case. Add TX timeout work/NAPI work to recover such case. Also increase the watchdog_timeo to 10 seconds, so more tolerant to error. Signed-off-by:

The queue index wrap around logic is based on power of 2 size depth. All queues are created with power of 2 depth. This increases the memory usage by the driver. This change is required for the next patches that avoids the power of 2 depth requirement for each of the queues. Update the function that increments producer index and consumer index during wrap around. Also, changes the index handling across multiple functions. Signed-off-by:
