Run the same in the system workqueue - netdev_hold when tx_timeout happens to protect against free_netdev if race occurs between rmmod and a tx timeout. netdev_put the reference when timeout task ends to progress freeing netdev V5: https://lore.kernel.org/all/20240129050254.3047778-1-srasheed@marvell.com/ - Changed unchecked return types to void and removed unnecessary initializations in [2/8] patch. V4: https://lore.kernel.org/all/20240108124213.2966536-1-srasheed@marvell.com/ - 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.
