[altq 1029] ALTQ & fragmented packets

["Paul Koster" <list@kosteronline.net>]

Does ALTQ handle fragmented packets? In particular can it classify
fragmented packets of flows specified by (source IP, dest IP, proto, source
port, dest port) and (source IP, dest IP, IPsecProto, SPI) ? (Especially
because the port numbers and SPI is not present in the fragments.)

I'm asking this because I'm experiencing end-to-end packet loss for an IPsec
flow, which suffers from fragmentation because of the additional ESP/AH
header size which makes it bigger than the MTU. From altqstat can be
concluded that the filter (source IP, dest IP, IPsecProto, SPI) is in place
and that the flow is correctly classified.
