Commit Message

Venkataramanan, Anirudh Sept. 20, 2018, 12:23 a.m. UTC
This patch continues the code move out of ice_main.c

The following top level functions (and related dependency functions) were
moved to ice_lib.c:
ice_vsi_alloc_rings
ice_vsi_set_rss_params
ice_vsi_set_num_qs
ice_get_free_slot
ice_vsi_init
ice_vsi_clear_rings
ice_vsi_alloc_arrays
