Subject: [PATCH net-next V2 01/21] mlx4_core: initial header-file changes
for SRIOV support
From: Jack Morgenstein <jackm@....mellanox.co.il>
These changes will not affect module operation as yet. They
are only to get some structs and enums in place for use by
subsequent patches (making those smaller).
Added here:
* sriov state structs and inlines (mlx4_is_master/slave/mfunc)
* comm-channel and vhcr support structures
* enum values for new FW and comm-channel virtual commands
(i.e., commands, passed via the comm channel to the PF-driver).
* prototypes for many command wrapper functions (used by the
PF context for processing FW commands passed to it by the VFs).
* struct mlx4_eqe is moved from eq.c to mlx4.h (it will be used
by other mlx4_core source files).
Signed-off-by: Jack Morgenstein <jackm@....mellanox.co.il>
