Subject: pppoe: fix /proc/net/pppoe
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=72fc939789dbe7ca091b50b686d45ac0df15417a;p=GitHub%2Fexynos8895%2Fandroid_kernel_samsung_universal8895.git

pppoe: fix /proc/net/pppoe

If a socket is hashed in last slot of pppoe hash table (PPPOE_HASH_SIZE-1)
we report it many times (up to filling seq buffer)
(Only the last socket of last slot)
