2016-08-20Remove the ie(4) driver for Intel 82586 ISA Ethernet adapters.John Baldwin
This driver only supports 10Mb Ethernet using PIO (the hardware supports DMA, but the driver only does PIO). There are not any PCCard adapters supported by this driver, only ISA cards. In addition, it does not use bus_space but instead uses bcopy with volatile pointers triggering a host of warnings. (if_ie.c is one of 3 files always built with -Wno-error) Relnotes: yes Notes: svn path=/head/; revision=304513
2016-04-10Cleanup unnecessary semicolons from the kernel.Pedro F. Giffuni
Found with devel/coccinelle. Notes: svn path=/head/; revision=297793
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.

queue length. The default value for this parameter is 50, which is quite low for many of today's uses and the only way to modify this parameter right now is to edit if_var.h file.

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

2008-06-05Rename the ie_EE16 module to just 'ie' so that at least one of the modulesJohn Baldwin
for this driver is called 'ie'. Otherwise, ifconfig(8) doesn't recognize any of the modules as being the ie(4) driver and will always try to kldload the driver even when it is already present in the kernel. Reported by: Thierry Herbelot Notes: svn path=/head/; revision=179559

avoid recursing on the lock. - Use IFQ_SET_MAXLEN(). Notes: svn path=/head/; revision=179558
2008-06-02Make ie(4) MPSAFE:John Baldwin
- Add a mutex to the softc and use it to protect the softc and device. - Setup the interrupt handler in the common code instead of in each front end and do it after ether_ifattach(). - Use ie_stop() and ieinit_locked() in iereset() rather than frobbing IFF_UP and invoking ieioctl(). - Use DELAY() to implement a spin loop on a register with a timeout rather than scheduling a timeout and then doing a tight spin on the register. In the non-MPSAFE case this would never have worked because the spinning code held Giant and the timeout routine would have been blocked on Giant forever. The same approach would not worke in the MPSAFE case either for the same reason, hence use a loop around DELAY(). - Clear IFF_DRV_(RUNNING|OACTIVE) in ie_stop() rather than in callers. - Call ieinit_locked() directly rather than ieioctl(!) from ie_mc_reset(). - Don't leak the rx frame buffer on detach.

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.

completenss. The pessimization is tiny compared with i/o port slowness except on very old machines, but code that used signed short types for i/o ports was unpessimized long ago, and the macro that detected it recently started working for u_short types too.
