Subject: Re: af_packet: when sending ethernet frames, parse header for skb->protocol
Date: Thu, 8 Aug 2013 02:03:03 +0400	[thread overview]
Message-ID: <20130807220303.GA3478@gmail.com> (raw)

Hi,

I compiled the akpm branch of linux-next and found that my virtual
machine didn't get an IP address by dhcp.

git bisect said that the problem is in "af_packet: when sending ethernet
frames, parse header for skb->protocol"

https://git.kernel.org/cgit/linux/kernel/git/next/linux-next.git/commit/?id=0f75b09c798ed00c30d7d5551b896be883bc2aeb

I have double checked, the VM gets an IP address w/o this patch and it
does not get an address with this patch.

Let me know if you need any information to investigate this issue.

Thanks.
