[PATCH iwl-next 0/2] ice: use ice_vsi_cfg_single_{r,t}xq in XSK

[PATCH iwl-next 0/2] ice: use ice_vsi_cfg_single_{r,t}xq in XSK

[Maciej Fijalkowski]

Ice driver has routines dedicated for configuring single queues. Let us
use them from ZC control path. This move will allow us to make
ice_vsi_cfg_{r,t}xq() static.

Thanks,
Maciej

[PATCH iwl-next 1/2] ice: make ice_vsi_cfg_rxq() static

[Maciej Fijalkowski]

Currently, XSK control path in ice driver calls directly
ice_vsi_cfg_rxq() whereas we have ice_vsi_cfg_single_rxq() for that
purpose. Use the latter from XSK side and make ice_vsi_cfg_rxq() static.

ice_vsi_cfg_rxq() resides in ice_base.c and is rather big, so to reduce
the code churn let us move two callers of it from ice_lib.c to
ice_base.c.

[PATCH iwl-next 2/2] ice: make ice_vsi_cfg_txq() static

[Maciej Fijalkowski]

Currently, XSK control path in ice driver calls directly
ice_vsi_cfg_txq() whereas we have ice_vsi_cfg_single_txq() for that
purpose. Use the latter from XSK side and make ice_vsi_cfg_txq() static.

ice_vsi_cfg_txq() resides in ice_base.c and is rather big, so to reduce
the code churn let us move the callers of it from ice_lib.c to
ice_base.c.

This change puts ice_qp_ena() on nice diet due to the checks and
operations that ice_vsi_cfg_single_{r,t}xq() do internally.
