2017-11-27sys/dev: further adoption of SPDX licensing ID tags.Pedro F. Giffuni
Mainly focus on files that use BSD 2-Clause license, however the tool I was using misidentified many licenses so this was mostly a manual - error prone - task. The Software Package Data Exchange (SPDX) group provides a specification to make it easier for automated tools to detect and summarize well known opensource licenses. We are gradually adopting the specification, noting that the tags are considered only advisory and do not, in any way, superceed or replace the license texts. Notes: svn path=/head/; revision=326255

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.

2009-11-19Several fixes to these drivers. Note that these two drivers are actuallyJohn Baldwin
just two different attachments (EISA and PCI) to a single driver. - Add real locking. Previously these drivers only acquired their lock in their interrupt handler or in the ioctl routine (but too broadly in the latter). No locking was used for the stack calling down into the driver via if_init() or if_start(), for device shutdown or detach. Also, the interrupt handler held the driver lock while calling if_input(). All this stuff should be fixed in the locking changes. - Really fix these drivers to handle if_alloc(). The front-end attachments were using if_initname() before the ifnet was allocated. Fix this by moving some of the duplicated logic from each driver into pdq_ifattach(). While here, make pdq_ifattach() return an error so that the driver just fails to attach if if_alloc() fails rather than panic'ing. Also, defer freeing the ifnet until the driver has stopped using it during detach. - Add a new private timer to drive the watchdog timer. - Pass the softc pointer to the interrupt handlers instead of the device_t so we can avoid the use of device_get_softc() and to better match what other drivers do. Notes: svn path=/head/; revision=199542
2009-06-26Use if_maddr_rlock()/if_maddr_runlock() rather than IF_ADDR_LOCK()/Robert Watson
IF_ADDR_UNLOCK() across network device drivers when accessing the per-interface multicast address list, if_multiaddrs. This will allow us to change the locking strategy without affecting our driver programming interface or binary interface. For two wireless drivers, remove unnecessary locking, since they don't actually access the multicast address list. Approved by: re (kib) MFC after: 6 weeks Notes: svn path=/head/; revision=195049

2005-08-09Propagate rename of IFF_OACTIVE and IFF_RUNNING to IFF_DRV_OACTIVE andRobert Watson
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.

2005-06-10Stop embedding struct ifnet at the top of driver softcs. Instead theBrooks Davis
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.
