Subject: Re: [PATCH 1/2] 3c59x: Add dma error checking and recovery

From: Neil Horman <>
Date: Wed, 17 Sep 2014 09:04:44 -0400

> Noted that 3c59x has no checks on transmit for failed DMA mappings, and no
> ability to unmap fragments when a single map fails in the middle of a transmit.
> This patch provides error checking to ensure that dma mappings work properly,
> and unrolls an skb mapping if a fragmented skb transmission has a mapping
> failure to prevent leaks.
