net: remove sb1000 cable modem driver

2025-03-21T16:11:54+00:00

This one is hilariously outdated, it provided a faster downlink over
TV cable for users of analog modems in the 1990s, through an ISA card.

The web page for the userspace tools has been broken for 25 years, and
the driver has only ever seen mechanical updates.

This driver can no longer be built since support for IBM Cell Blades was
removed, in particular PPC_IBM_CELL_BLADE.

Remove the driver and the documentation.
Remove the MAINTAINERS entry, and add Ishizaki and Geoff to CREDITS.

i40e: add ability to reset VF for Tx and Rx MDD events

2025-01-08T02:16:02+00:00

Implement "mdd-auto-reset-vf" priv-flag to handle Tx and Rx MDD events for VFs.
This flag is also used in other network adapters like ICE.

Usage:
- "on"  - The problematic VF will be automatically reset
	  if a malformed descriptor is detected.
- "off" - The problematic VF will be disabled.

In cases where a VF sends malformed packets classified as malicious, it can
cause the Tx queue to freeze, rendering it unusable for several minutes. When
an MDD event occurs, this new implementation allows for a graceful VF reset to
quickly restore operational state.

Currently, VF queues are disabled if an MDD event occurs. This patch adds the
ability to reset the VF if a Tx or Rx MDD event occurs. It also includes MDD
event logging throttling to avoid dmesg pollution and unifies the format of
Tx and Rx MDD messages.

Note: Standard message rate limiting functions like dev_info_ratelimited()
do not meet our requirements. Custom rate limiting is implemented,
please see the code for details.

eth: fbnic: add RPC hardware statistics

Report Rx parser statistics via ethtool -S.

The parser stats are 32b, so we need to add refresh to the service
task to make sure we don't miss overflows.

eth: fbnic: add PCIe hardware statistics

2024-11-19T02:43:41+00:00

Add PCIe hardware statistics support to the fbnic driver. These stats
provide insight into PCIe transaction performance and error conditions.

Which includes, read/write and completion TLP counts and DWORD counts and
debug counters for tag, completion credit and NP credit exhaustion

The stats are exposed via debugfs and can be used to monitor PCIe
performance and debug PCIe issues.
