RE: Inconsistency between net/if.c and several ethernet drivers

RE: Inconsistency between net/if.c and several ethernet drivers

Any driver that uses miibus_attach() is broken if struct arpcom is not at the beginning of the softc structure. There was some discussion of this more than a year ago when this bug showed up in the wx driver. Jim > -Original Message- > From: [EMAIL PROTECTED] > [mailto:[EMAIL PROTECTED]

Re: Inconsistency between net/if.c and several ethernet drivers

Pointers to interface and arpcom are clearly equivalent as arpcom contains the interface structure. The one definition for the combined structure makes it very safe. However, there are many definitions of the softc structure. Requiring arpcom to be at the beginning of all softc structs require

hi = Hardware configuration I am running : - FreeBSD 4.6 Release SMP The machine contains the following hardware - ASUS CU4VX Motherboard Dual Processor (with 1 onboard fxp ethernet interface) - FORERUNNER PCA200E ATM Adapter (hfa) - DLINK 500SX Gigabit Fiber SX Ether

ip options on udp sockets

Why are IP options not passed to userland on a udp socket? (and on all other transport protocols for that matter) We created such an implementation by just returning it in the ancillary data control message. (Only for IP timestamps which we needed but this could be easily done for all IP options)

IP Fragmentation

Hi, I am writing a gigabit ethernet driver for one of the NICs.My hardware is capable of computing the checksum and hence I am enabling per-packet handling of TCP/IP/UDP checksum offload in transmit side.I would like to know if there is a way by which I can tell the upperguy that I will not be abl
