Merge branch 'eth-fbnic-extend-hw-stats-support'
Jakub Kicinski says: ==================== eth: fbnic: Extend hw stats support Mohsin says: Extend hardware stats support for fbnic by adding the ability to reset hardware stats when the device experience a reset due to a PCI error and include MAC stats in the hardware stats reset. Additionally, expand hardware stats coverage to include FEC, PHY, and Pause stats. v1: https://lore.kernel.org/20250822164731.1461754-1-kuba@kernel.org ==================== Link: https://patch.msgid.link/20250825200206.2357713-1-kuba@kernel.org Signed-off-by: Jakub Kicinski <kuba@kernel.org>
