pktgen: do not abuse IN6_ADDR_HSIZE

pktgen accidentally used IN6_ADDR_HSIZE, instead of using the size of an IPv6 address. Since IN6_ADDR_HSIZE recently was increased from 16 to 256, this old bug is hitting us. Fixes: 3f27fb2 ("ipv6: addrconf: add per netns perturbation in inet6_addr_hash()") Signed-off-by: Eric Dumazet <[email protected]> Reported-by: Dan Carpenter <[email protected]> Signed-off-by: David S.
