2021-10-22Retire synchronous PPP kernel driver sppp(4).Gleb Smirnoff
The last two drivers that required sppp are cp(4) and ce(4). These devices are still produced and can be purchased at Cronyx <http://cronyx.ru/hardware/wan.html>. Since Roman Kurakin <rik@FreeBSD.org> has quit them, they no longer support FreeBSD officially. Later they have dropped support for Linux drivers to. As of mid-2020 they don't even have a developer to maintain their Windows driver. However, their support verbally told me that they could provide aid to a FreeBSD developer with documentaion in case if there appears a new customer for their devices. These drivers have a feature to not use sppp(4) and create an interface, but instead expose the device as netgraph(4) node. Then, you can attach ng_ppp(4) with help of ports/net/mpd5 on top of the node and get your synchronous PPP. Alternatively you can attach ng_frame_relay(4) or ng_cisco(4) for HDLC. Actually, last time I used cp(4) back in 2004, using netgraph(4) instead of sppp(4) was already the right way to do. Thus, remove the sppp(4) related part of the drivers and enable by default the negraph(4) part. Further maintenance of these drivers in the tree shouldn't be a big deal. While doing that, remove some cruft and enable cp(4) compilation on amd64. The ce(4) for some unknown reason marks its internal DDK functions with __attribute__ fastcall, which most likely is safe to remove, but without hardware I'm not going to do that, so ce(4) remains i386-only.

2015-01-06In order to reduce use of M_EXT outside of the mbuf allocator andRobert Watson
socket-buffer implementations, introduce a return value for MCLGET() (and m_cljget() that underlies it) to allow the caller to avoid testing M_EXT itself. Update all callers to use the return value. With this change, very few network device drivers remain aware of M_EXT; the primary exceptions lie in mbuf-chain pretty printers for debugging, and in a few cases, custom mbuf and cluster allocation implementations. NB: This is a difficult-to-test change as it touches many drivers for which I don't have physical devices. Instead we've gone for intensive review, but further post-commit review would definitely be appreciated to spot errors where changes could not easily be made mechanically, but were largely mechanical in nature.

2008-09-27Replace all calls to minor() with dev2unit().Ed Schouten
After I removed all the unit2minor()/minor2unit() calls from the kernel yesterday, I realised calling minor() everywhere is quite confusing. Character devices now only have the ability to store a unit number, not a minor number. Remove the confusion by using dev2unit() everywhere. This commit could also be considered as a bug fix. A lot of drivers call minor(), while they should actually be calling dev2unit(). In -CURRENT this isn't a problem, but it turns out we never had any problem reports related to that issue in the past. I suspect not many people connect more than 256 pieces of the same hardware. Reviewed by: kib Notes: svn path=/head/; revision=183397
