Subject: [PATCH] pgm: don't advance bp by the option haeder length twice.
|
|
|
|
At those points, we've already advanced it by the option header length,
|
|
and opt_len includes that length, so advance bp by opt_len minus the
|
|
option header length.
|
|
|
|
(cherry picked from commit 09b0447fad52298440e05e7368f9d24492d0b0fe)
