Subject: [PATCH net-next v4 0/8] add octeon_ep_vf driver

This driver implements networking functionality of Marvell's Octeon
PCI Endpoint NIC VF.

This driver support following devices:
 * Network controller: Cavium, Inc. Device b203
 * Network controller: Cavium, Inc. Device b403
 * Network controller: Cavium, Inc. Device b103
 * Network controller: Cavium, Inc. Device b903
 * Network controller: Cavium, Inc. Device ba03
 * Network controller: Cavium, Inc. Device bc03
 * Network controller: Cavium, Inc. Device bd03

Changes:
V4:
  - Moved some stats from ethtool and added more to ndo_get_stats64
  - Replaced code in IQ full check function to use helper from
    net/netdev_queues.h
  - Refactored code so that NETDEV_TX_BUSY is avoided

V3: https://lore.kernel.org/all/20240105203823.2953604-1-srasheed@marvell.com/
  - Removed UINT64_MAX, which is unused
  - Replaced masks and ULL declarations with GENMASK_ULL(), ULL() and
    other linux/bits.h macros, corrected declarations to conform to xmas tree format in patch [2/8]
  - Moved vfree and vzalloc null pointer casting corrections to patch
    [3/8], and corrected return values to follow standard kernel error codes in same
   - Set static budget of 64 for tx completion processing in NAPI
  - Replaces napi_complete and build_skb APIs to napi_complete_done and
    napi_build_skb APIs respectively
  - Replaced code with helper from net/netdev_queues.h to wake queues in TX completion
    processing
  - Removed duplicate reporting of TX/RX packets/bytes, which is already
    done during ndo_get_stats64

V2: https://lore.kernel.org/all/20231223134000.2906144-1-srasheed@marvell.com/
  - Removed linux/version.h header file from inclusion in
    octep_vf_main.c
  - Corrected Makefile entry to include building octep_vf_mbox.c in
    [6/8] patch.
  - Removed redundant vzalloc pointer cast and vfree pointer check in
    [6/8] patch.

V1: https://lore.kernel.org/all/20231221092844.2885872-1-srasheed@marvell.com/
