Hi Roland,
Missed out one bug fix in patch 14/30 for the `ocrdma` driver.
Resubmitting the series again with this patch fixed
Apologies for any inconvenience.
Thanks

> Subject: [PATCH 00/30] IB/Core: Adding support for RoCEV2 Specification
>
> Hi Roland,
>
> This patch series was created out of collaboration between Emulex and
> Mellanox.
> While Emulex sent out the RoCEV2 patch first to the community, Mellanox
> which was also working on some core infrastructure changes from the
> ground-up towards
> RoCEV2 felt that the RoCEV2 patch would be better served if done on top of
> their basic infrastructure changes to associate entities like MAC, VLAN, IP
> Address with GIDs and thereby move GID Table Management from HW
> Vendor drivers to IB/Core.
> This patchset is the result of joint development effort between the two
> teams.
>
> Patch 0001 creates a new infrastructure for storing GIDs and their attributes
> in IB/core. This infrastructure support lock-less read of GIDs using a
> sequence
> number. The data structure is initialized only for RoCE ports.
> Every gid has meta information describes its related net device and its type.
>
> Patches 0002, 0004 and 0005 add population of this table for various cases
> based on net device events. We always enable default gids for an active
> device (an active device is defined here as a device that doesn't have a
> bonding master or is the current active slave). This is done in order to allow
> loopback traffic
>
> Patch 0005 adds proper bonding support - only the active slaves retain their
> master's IP based gids and default gids.
>
> This whole concept needs to fit the existing sysfs model, thus patch 0006
> adds sysfs entries that represent the net device and gid type related to each
> gid.
>
> Patches 0002, 0007, 0008 and 0009 changes the rest of IB/core to fit the new
> model.
> Instead of storing smac and vlan, we store either if_index, gid and gid_type
> or sgid_index. Either set suffices in order to resolve all the required
> Ethernet
> parameters. ib_init_ah_from_wc was changed, such as that when a wc is
> arrived, we query all the net devices in all namespaces trying to find a
> match.
> This match is later used to find an appropriate sgid_index.
>
> Patch 0010 is used in order to configure the default mode of the cma.
> In order to avoid changing existing rdma-cm applications, we adds a configfs
> that states for each ib device what's the default RoCE mode.
>
> Patch 0011 mainly corrects the hop limit value and adds a hint about RoCE
> type according to whether we have a gateway. This is the patch that makes it
> possible for applications to seamlessly interop between RoCE V1 and V2
> without undergoing any changes themselves.
>
> The rest of the patches add support for ocrdma and mlx4 devices.
>
> This series depends on RoCE LAG series (already accepted in net-next tree)
