* Fix a bug originally introduced in rev. 1.74; don't reloaded themarius2006-12-201-1/+2
| | | | | | | | | | watchdog timer in dc_txeof() in case there are still unhandled descriptors as dc_poll() invokes dc_poll() unconditionally. Otherwise this would result in the watchdog timer constantly being being reloaded and thus circumvent that the watchdog ever fires in the DEVICE_POLLING case. Pointed out by: bde

* - Rev. 1.175 fixed compilation on sparc64 but also backed out zeroing ofmarius2005-12-051-5/+2
| | | | | | | | | | | | | | the eaddr array (introduced in rev. 1.174) prior to writing to it. As dc_read_eeprom() is told to write only 3 16-bit words to eaddr but eaddr in fact is somewhat larger removal of the zeroing defeated the check whether the MAC address is all zero as there can be some random garbage in eaddr past the 3 words written to it and the check verifys all bits in eaddr. Solve this by changing the check to verify only the 3 words (happenning to be ETHER_ADDR_LEN bytes) written to eaddr. - While here change the notation of "FCode" in a nearby comment to the official way.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | o Axe poll in trap. o Axe IFF_POLLING flag from if_flags. o Rework revision 1.21 (Giant removal), in such a way that poll_mtx is not dropped during call to polling handler. This fixes problem with idle polling. o Make registration and deregistration from polling in a functional way, insted of next tick/interrupt. o Obsolete kern.polling.enable. Polling is turned on/off with ifconfig. Detailed kern_poll.c changes: - Remove polling handler flags, introduced in 1.21. The are not needed now. - Forget and do not check if_flags, if_capenable and if_drv_flags. - Call all registered polling handlers unconditionally. - Do not drop poll_mtx, when entering polling handlers. - In ether_poll() NET_LOCK_GIANT prior to locking poll_mtx. - In netisr_poll() axe the block, where polling code asks drivers to unregister. - In netisr_poll() and ether_poll() do polling always, if any handlers are present. - In ether_poll_[de]register() remove a lot of error hiding code. Assert that arguments are correct, instead. - In ether_poll_[de]register() use standard return values in case of error or success. - Introduce poll_switch() that is a sysctl handler for kern.polling.enable. poll_switch() goes through interface list and enabled/disables polling. A message that kern.polling.enable is deprecated is printed. Detailed driver changes: - On attach driver announces IFCAP_POLLING in if_capabilities, but not in if_capenable. - On detach driver calls ether_poll_deregister() if polling is enabled. - In polling handler driver obtains its lock and checks IFF_DRV_RUNNING flag. If there is no, then unlocks and returns. - In ioctl handler driver checks for IFCAP_POLLING flag requested to be set or cleared. Driver first calls ether_poll_[de]register(), then obtains driver lock and [dis/en]ables interrupts. - In interrupt handler driver checks IFCAP_POLLING flag in if_capenable. If present, then returns.This is important to protect from spurious interrupts. Reviewed by: ru, sam, jhb

Device drivers are now responsible for synchronizing access to these flags, as they are in if_drv_flags.

* Stop embedding struct ifnet at the top of driver softcs. Instead thebrooks2005-06-102-25/+31
| | | | | | | | | | | | | | | | | | | | 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.

If set to "true" OF_getetheraddr() will now return the unique MAC address stored in the "local-mac-address" property of the device's OFW node if present and the host address/system default MAC address if the node doesn't doesn't have such a property. If set to "false" the host address will be returned for all devices like before this change. This brings the behaviour of device drivers for NICs with OFW support/ FCode, i.e. dc(4) for on-board DM9102A on Sun machines, gem(4) and hme(4), regarding "local-mac-address?" in line with NetBSD and Solaris.
