Already dealt with in net-next-2.6, please act against the
active networking development trees when fixing warnings and
doing cleanups.

Thank you.

    ppp_generic: Help GCC see that 'flen' is always initialized.
    
    It's too stupid to see that we always set flen to something
    before we use it in ppp_mp_explode():
    
    drivers/net/ppp_generic.c: In function 'ppp_push':
    drivers/net/ppp_generic.c:1314: warning: 'flen' may be used uninitialized in this function
    drivers/net/ppp_generic.c:1314: note: 'flen' was declared here
    
    This started warning after commit a53a8b56827cc429c6d9f861ad558beeb5f6103f
    ("ppp: fix lost fragments in ppp_mp_explode() (resubmit)")
    
    So just put an explicit unconditional initialization there to
    hush it up.
