Revision a66ed149b0da5b97fa7486ee2bcd00f3f9df5442 authored by Parav Pandit on 23 April 2018, 13:58:17 UTC, committed by Doug Ledford on 23 April 2018, 21:26:04 UTC
Default GIDs are marked reserved at the start of the GID table at index
0 and 1 by gid_table_reserve_default(). Currently when default GID is
requested, it can still allocates an empty slot which was not marked as
RESERVED for default GID, which is incorrect.
At least in current code flow of roce_gid_mgmt.c, in theory we can
still request to allocate more than one/two default GIDs depending
on how upper devices are setup.
Therefore, it is better for cache layer to only allow our reserved slots
to be used by default GID allocation requests.
