Subject: ICMP packets - ll_temac with Microblaze
Date: Wed, 21 Dec 2011 11:11:37 +0100 [thread overview]
Message-ID: <4EF1B0D9.2010007@monstr.eu> (raw)
Hi Eric and David,
I have found one problem with ll_temac driver and
this commit: net: more accurate skb truesize
sha1: 87fb4b7b533073eeeaed0b6bf7c2328995f6c075
The problem is only with icmp packets from the target. It is sent and driver receive it
but it is not proceed to the application.
The problem I see is that kmalloc_node_track_caller allocate
specific size and then this size is changed by SKB_WITH_OVERHEAD(ksize(data)).
The problem is with netdev_alloc_skb_ip_align which calls __alloc_skb function.
Currently driver uses setting for jumbo frames (9k). When I change it to use mtu (1,5k) then
everything is ok.
Can you give me some hints what can be wrong?
Thanks,
Michal
