The limit parameter for SFQ qdiscs isn''t listed in the howto. Based on
a mail from this list from 4 may 2002 ("SFQ queue lengths -
generalization"), I''d guess it limits the number of packets/bytes
in
in the queue, but wether it does so by number of bytes, packets, or
time spent in the queue I don''t know. Perhaps someone in the know
could add a line to the howto?

Could someone with write access to the HOWTO add this? -- Frank v Waveren Fingerprint: 21A7 C7F3 fvw@[var.cx|stack.nl|chello.nl] ICQ#10074100 1FF3 47FF 545C CB53 Public key: hkp://wwwkeys.pgp.net/fvw@var.cx 7BD9 09C0 3AC1 6DF2 _______________________________________________ LARTC mailing list / LARTC@mailman.ds9a.nl http://mailman.ds9a.nl/mailman/listinfo/lartc HOWTO: http://lartc.org/
