check += __constant_htons(0x0100);
iph->check = check + (check>=0xFFFF);
return --iph->ttl;
------------End patch
The expression check>=0xFFFF could only be true(1) when (u16)check ==
0xFFFF, not what is it meant to be.
This is fixed exactly like this patch in 2.4.x.
Kernel 2.2.19 also has the same problems.
