IB-core and rdma-core restrict the sgid_index specified by users, which is uint8_t/u8 data type, to only be within the range of 0-255, so it's meaningless to support excessively large gid_table_len. On the other hand, ib-core creates as many sysfs gid files as gid_table_len, most of which are not only useless because of the reason above, but also greatly increase the traversal time of the sysfs gid files for applications. This patch limits the maximum length of gid table to 256. Signed-off-by:

Now, different devices may have the same interrupt name, which makes it difficult for users to distinguish between these interrupts. Modify the naming style to be consistent with our network devices. Before: "hns-aeq-0" "hns-ceq-0" ... Now: "hns-0000:35:00.0-aeq-0" "hns-0000:35:00.0-ceq-0" ... Signed-off-by:

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:
