>Description:
"ip length 314 disagrees with bytes received 534" message diplays whenever
renewing dhcp lease with router:

DHCPREQUEST on rl0 to 255.255.255.255 port 67
ip length 314 disagrees with bytes received 534.
accepting packet with data after udp payload.
DHCPACK from 192.168.0.1
bound to 192.168.0.4 -- renewal in 1013730269 seconds.

However, I do not seem to have symptoms others have reported in bsd forums,
like unable to ping yahoo.com. I can ping and dig is working.
>How-To-Repeat:
1. reboot (then see: 'dmesg -a |grep disag' output) or,
2. run: # /sbin/dhclient on your nic
>Fix:
unknown. IPv6 suspected. Please contact me to request further system info.

State-Changed-Why:  
It seems fairly unlikely this has anything to do with dhclient.  I'm 
betting on a driver bug or something with bpf.  Does this still occur in 
6-STABLE?  What network interface and dhcp server are you using?

State-Changed-When: Sat May 13 04:07:29 UTC 2006 
State-Changed-Why:  
I've actually got a router/AP that produces this output on both 
wired and wireless networks so I'll get to looking at it eventually. 
My guess is that it's a buggy behavior in the device and we'll just 
end up wanting to turn this printout off.

State-Changed-When: Mon Jan 15 17:20:04 UTC 2007 
State-Changed-Why:  
I think this has been fixed in 6-STABLE and HEAD as of bpf.c revs 
1.2.2.4 and 1.7 respectivly (6.2-RELEASE contains this revison). 

Can you confirm this? 

To check the revision of the bpf.c used in your dhclient use: 

ident /sbin/dhclient | grep bpf 

Thanks, 
Brooks

I thought I'd fixed this, but discoved I hadn't and forgot to switch the 
state out of feedback so re-open this.
