IB/core: Add gid_type to gid attribute

2015-12-23T15:35:10+00:00

In order to support multiple GID types, we need to store the gid_type
with each GID. This is also aligned with the RoCE v2 annex "RoCEv2 PORT
GID table entries shall have a "GID type" attribute that denotes the L3
Address type". The currently supported GID is IB_GID_TYPE_IB which is
also RoCE v1 GID type.

This implies that gid_type should be added to roce_gid_table meta-data.

IB/cache: Add ib_find_gid_by_filter cache API

2015-10-22T03:48:17+00:00

GID cache API users might want to search for GIDs with specific
attributes rather than just specifying GID, net device and port.
This is used in a later patch, where we find the sgid index by
L2 Ethernet attributes.

IB/core: Expose and rename ib_find_cached_gid_by_port cache API

2015-10-22T03:48:17+00:00

Sometime consumers might want to search for a GID in a specific port.
For example, when a WC arrives and we want to search the GID
that matches that port - it's better to search only the relevant
port.
Exposing and renaming ib_cache_gid_find_by_port in order to match
the naming convention of the module.

IB/core: Add netdev and gid attributes paramteres to cache

2015-10-22T03:48:17+00:00

Adding an ability to query the IB cache by a netdev and get the
attributes of a GID. These parameters are necessary in order to
successfully resolve the required GID (when the netdevice is known)
and get the Ethernet L2 attributes from a GID.

IB/core cleanup: Add const to args - agent_send_response

In order to support constant callers of agent_send_response we add const
specifiers to the its pointer arguments.

Adjust the call tree accordingly.

IB/core: Add ib_find_exact_cached_pkey()

2012-10-01T03:33:30+00:00

When P_Key tables potentially contain both full and partial membership
copies for the same P_Key, we need a function to find the index for an
exact (16-bit) P_Key.

This is necessary when the master forwards QP1 MADs sent by guests.
If the guest has sent the MAD with a limited membership P_Key, we need
to to forward the MAD using the same limited membership P_Key.  Since
the master may have both the limited and the full member P_Keys in its
table, we must make sure to retrieve the limited membership P_Key in
this case.

[PATCH] IB: move include files to include/rdma

2005-08-27T03:37:38+00:00

Move the InfiniBand headers from drivers/infiniband/include to include/rdma.
This allows InfiniBand-using code to live elsewhere, and lets us remove the
ugly EXTRA_CFLAGS include path from the InfiniBand Makefiles.
