Burst Feature

2003-09-05 Thread Ivo Vachkov

2003-09-05 Thread Andrew Gallatin
In FreeBSD 5 are IP frags guaranteed to be passed to a network driver with no intermediary IP packets between the fragments? Or can multiple streams get queued at once? Specifically, if a driver claims to be able to CSUM_IP_FRAGS, can it count on getting all the frags, one right after another (p

Reserving a couple of names for custom developed netgraph nodes
