Subject: [PATCH net-next v5 0/2] Add Frame Preemption MAC Merge support for ICSSG
Date: Thu, 30 Apr 2026 16:47:21 +0530 [thread overview]
Message-ID: <20260430111723.497113-1-m-malladi@ti.com> (raw)
This patch series adds QoS support to the ICSSG PRUETH driver.
The first patch implements mqprio qdisc handling and TC offload hooks
so userspace can request TC mappings and queue counts.
It also integrates a driver-side mechanism to program the firmware
with the IET/FPE preemption mask and to kick the firmware verify state
machine when frame preemption is enabled. The second patch adds ethtool
perations for the MAC Merge (Frame Preemption) sublayer, exposing .get_mm,
.set_mm and .get_mm_stats so admins can view and change MAC Merge
parameters and retrieve preemption statistics.
