Assuming that the CHECKSUM_UNNECESSARY line wasn't there, then the
problem is simply that your packet has the wrong UDP checksum.
So I suggest that you print the packet out and compare it with
the
Hi Herbert,
Things seem to be more clear for me.
When not in netpoll mode, before an udp package passed to udp_rcv,
the ip layer will call the routine __skb_checksum_complete(skb);
to do the checksum. After ip checksum, skb-ip_summed will be
assigned to CHECKSUM_UNNECESSARY.
Hi Herbert,
The following change works properly on my side, it just do the same
thing as the driver not in netpoll mode. Let me know it's acceptable,
please.
Thanks,

This doesn't make sense. First of

Hi Herbert - I'm working on blackfin uclinux platform. My network

The driver is attached.
Could you please add a printk in checksum_udp to print out the pertinent

The changes to how hardware receive checksums are handled broke
the netpoll checksum code (for CHECKSUM_HW). Since this is not at
all performance critical, try this patch. It changes to always to
normal software checksum.
