| | | | | | | | | | | | | | | | | | | | | | | the NIC drivers as well as the PHY drivers to take advantage of the mii_attach() introduced in r213878 to get rid of certain hacks. For the most part these were: - Artificially limiting miibus_{read,write}reg methods to certain PHY addresses; we now let mii_attach() only probe the PHY at the desired address(es) instead. - PHY drivers setting MIIF_* flags based on the NIC driver they hang off from, partly even based on grabbing and using the softc of the parent; we now pass these flags down from the NIC to the PHY drivers via mii_attach(). This got us rid of all such hacks except those of brgphy() in combination with bce(4) and bge(4), which is way beyond what can be expressed with simple flags. While at it, I took the opportunity to change the NIC drivers to pass up the error returned by mii_attach() (previously by mii_phy_probe()) and unify the error message used in this case where and as appropriate as mii_attach() actually can fail for a number of reasons, not just because of no PHY(s) being present at the expected address(es).

* - Don't set CAS_PCS_DATAPATH to anything except CAS_PCS_DATAPATH_SERDESmarius2010-05-032-70/+174
| | | | | | | | | | | | | | | | | on Cassini using the external PCS SERDES otherwise unaligned access traps and other strange effects happen with some machines. Don't touch the MIF which is unused in that case either. These changes require the PHY type to use to be determined via the OFW device tree or from the VPD in machines without the former. - Disable the SERDES pins of Saturn when not used in order to save power and ensure they are enabled otherwise. - In cas_attach() use the correct register offset for CAS_PCS_CONF_EN. - Add some bus space barriers missing in the PCS code path. These changes make the Sun GigaSwift Ethernet 1.0 MMF cards as well as the on-board interfaces found in Sun Fire B100s Blade Server work. PR: 144867
* Use if_maddr_rlock()/if_maddr_runlock() rather than IF_ADDR_LOCK()/rwatson2009-06-261-2/+2
| | | | | | | | | | | | | 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

* - Change this driver to do taskqueue(9) based TX and interruptmarius2009-06-242-57/+136
| | | | | | | | | | | | | | | | | | | | handling in order to reduce interrupt overhead which results in better performance. - Call ether_ifdetach(9) before stopping the controller and the callouts detach in order to prevent active BPF listeners to clear promiscuous mode which may lead to the tick callout being restarted which will trigger a panic once it's actually gone. - Add explicit IFF_DRV_RUNNING checking in order to prevent extra link up/down events when using dhclient(8). - Use the correct macro for deciding whether 2/3 of the available TX descriptors are used. - Wrap the RX fault printing in #ifdef CAS_DEBUG in order to not unnecessarily frighten users and as debugging was the actual intention. Real errors caused by these faults still will be accumulated as input errors. It might be a good idea to later on add driver specific counters for the faults though.

* Add cas(4), a driver for Sun Cassini/Cassini+ and National Semiconductormarius2009-06-153-0/+4034
DP83065 Saturn Gigabit Ethernet controllers. These are the successors of the Sun GEM controllers and still have a similar but extended transmit logic. As such this driver is based on gem(4). Thanks to marcel@ for providing a Sun Quad GigaSwift Ethernet UTP (QGE) card which was vital for getting this driver to work on architectures not using Open Firmware.
