Hi Doug, Previously, the hop limit of RoCE packets were set to IPV6_DEFAULT_HOPLIMIT. This generally works, but RoCE stack needs to follow the IP stack rules. Therefore, this patch series use ip4_dst_hoplimit and ip6_dst_hoplimit in order to set the correct hop limit for RoCE traffic.
The first patch refactors the name of rdma_addr_find_dmac_by_grh to rdma_addr_find_l2_eth_by_grh while the second one does the actual change. Regards, Matan Changes from V0: - Hop limit in IB when using reversible path should be 0xff.
