Subject: [PATCH net-next 0/3] net/mlx5e: RX datapath enhancements
Date: Mon, 12 Jan 2026 15:22:06 +0200	[thread overview]
Message-ID: <1768224129-1600265-1-git-send-email-tariqt@nvidia.com> (raw)

Hi,

This series by Dragos introduces multiple RX datapath enhancements to
the mlx5e driver.

First patch adds SW handling for oversized packets in non-linear SKB
mode.

Second patch adds a reclaim mechanism to mitigate memory allocation
failures with memory providers.

Third patch moves SHAMPO to use static memory for the headers, rather
than replenishing the memory from a page_pool.
This introduces an interesting performance tradeoff where copying the
header pays off.

Regards,
Tariq

  net/mlx5e: SHAMPO, Improve allocation recovery
