hinic3: module initialization and tx/rx logic

2025-05-22T03:31:42+00:00

This is [1/3] part of hinic3 Ethernet driver initial submission.
With this patch hinic3 is a valid kernel module but non-functional
driver.

The driver parts contained in this patch:
Module initialization.
PCI driver registration but with empty id_table.
Auxiliary driver registration.
Net device_ops registration but open/stop are empty stubs.
tx/rx logic.

All major data structures of the driver are fully introduced with the
code that uses them but without their initialization code that requires
management interface with the hw.

eth: fbnic: Add devlink dev flash support

2025-05-15T10:59:18+00:00

Add support to update the CMRT and control firmware as well as the UEFI
driver on fbnic using devlink dev flash.

Make sure the shutdown / quiescence paths like suspend take the devlink
lock to prevent them from interrupting the FW flashing process.

net: ti: icssg-prueth: Add ICSSG FW Stats

2025-04-29T00:20:53+00:00

The ICSSG firmware maintains set of stats called PA_STATS.
Currently the driver only dumps 4 stats. Add support for dumping more
stats.

The offset for different stats are defined as MACROs in icssg_switch_map.h
file. All the offsets are for Slice0. Slice1 offsets are slice0 + 4.
The offset calculation is taken care while reading the stats in
emac_update_hardware_stats().

The statistics are documented in
Documentation/networking/device_drivers/icssg_prueth.rst

eth: fbnic: add support for TMI stats

2025-04-15T09:23:13+00:00

This patch add coverage for TMI stats including PTP stats and drop
stats.

PTP stats include illegal requests, bad timestamp and good timestamps.
The bad timestamp and illegal request counters are reported under as
`error` via `ethtool -T` Both these counters are individually being
reported via `ethtool -S`

The good timestamp stats are being reported as `pkts` via `ethtool -T`

eth: fbnic: add coverage for RXB stats

2025-04-15T09:23:13+00:00

This patch provides coverage to the RXB (RX Buffer) stats. RXB stats
are divided into 3 sections: RXB enqueue, RXB FIFO, and RXB dequeue
stats.

The RXB enqueue/dequeue stats are indexed from 0-3 and cater for the
input/output counters whereas, the RXB fifo stats are indexed from 0-7.

The RXB also supports pause frame stats counters which we are leaving
for a later patch.

ethtool -S eth0 | grep rxb

eth: fbnic: add coverage for hw queue stats

2025-04-15T09:23:13+00:00

This patch provides support for hardware queue stats and covers
packet errors for RX-DMA engine, RCQ drops and BDQ drops.

The packet errors are also aggregated with the `rx_errors` stats in the
`rtnl_link_stats` as well as with the `hw_drops` in the queue API.

The RCQ and BDQ drops are aggregated with `rx_over_errors` in the
`rtnl_link_stats` as well as with the `hw_drop_overruns` in the queue API.

ethtool -S eth0 | grep -E 'rde'
