* Remove the NATM framework including the en(4), fatm(4), hatm(4), andBrooks Davis2017-04-241-337/+0
| | | | | | | | | | | | | | | | | | | | | | | | patm(4) devices. Maintaining an address family and framework has real costs when we make infrastructure improvements. In the case of NATM we support no devices manufactured in the last 20 years and some will not even work in modern motherboards (some newer devices that patm(4) could be updated to support apparently exist, but we do not currently have support). With this change, support remains for some netgraph modules that don't require NATM support code. It is unclear if all these should remain, though ng_atmllc certainly stands alone. Note well: FreeBSD 11 supports NATM and will continue to do so until at least September 30, 2021. Improvements to the code in FreeBSD 11 are certainly welcome.

| | | | | | | | | | | | | | | | | IFF_DRV_RUNNING, as well as the move from ifnet.if_flags to ifnet.if_drv_flags. Device drivers are now responsible for synchronizing access to these flags, as they are in if_drv_flags. This helps prevent races between the network stack and device driver in maintaining the interface flags field. Many __FreeBSD__ and __FreeBSD_version checks maintained and continued; some less so.

* Stop embedding struct ifnet at the top of driver softcs. Instead theBrooks Davis2005-06-101-6/+7
| | | | | | | | | | | | | | | | | | | | | | | struct ifnet or the layer 2 common structure it was embedded in have been replaced with a struct ifnet pointer to be filled by a call to the new function, if_alloc(). The layer 2 common structure is also allocated via if_alloc() based on the interface type. It is hung off the new struct ifnet member, if_l2com. This change removes the size of these structures from the kernel ABI and will allow us to better manage them as interfaces come and go. Other changes of note: - Struct arpcom is no longer referenced in normal interface code. Instead the Ethernet address is accessed via the IFP2ENADDR() macro. To enforce this ac_enaddr has been renamed to _ac_enaddr. - The second argument to ether_ifattach is now always the mac address from driver private storage rather than sometimes being ac_enaddr.

In fact, the inserting macro treated its argument as an opposite host order short and the calling code feeds it the result of htons(). This happens to work on i386, but fails on sparc.

(bpfwrite should work if atm_pseudohdr and LLC/SNAP are prepended.) - BPF link type is changed to DLT_ATM_RFC1483. BPF now understands only LLC/SNAP!! (because bpf can't handle variable link header length.) It is recommended to use LLC/SNAP instead of NULL encapsulation for various reasons.
