* MFC r232019,232021,232025,232027,232029,232040:Pyun YongHyeon2012-03-262-42/+45
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | r232019: Give hardware chance to drain active DMA cycles. r232021: If there are not enough RX buffers, release partially allocated RX buffers. r232025: Introduce sf_ifmedia_upd_locked() and have driver reset PHY before switching to selected media. While here, set if_drv_flags before switching to selected media. r232027: No need to reprogram hardware RX filter when driver is not running. r232029: Remove taskqueue based MII stat change handler. Driver does not need deferred link state change processing. While I'm here, do not report current link status if interface is not UP. r232040: Add check for IFF_DRV_RUNNING flag after serving an interrupt and don't give RX path more priority than TX path. Also remove infinite loop in interrupt handler and limit number of iteration to 32. This change addresses system load fluctuations under high network load. Notes: svn path=/stable/7/; revision=233488
* MFC: r221407 (partial)Marius Strobl2011-09-111-5/+3
| | | | | | | | | | | | | | | | | | | | | | | | - Let mii_phy_add_media() also announce the support of IFM_NONE. - Add a PHY-specific reset routine is for lxtphy(4) which disables MII interrupts. - Remove redundant checks in NIC drivers for mii->mii_instance not being zero before calling the reset routines because as soon as one PHY driver attaches mii->mii_instance is incremented and we hardly can end up in their media change callbacks etc if no PHY driver has attached as mii_attach() would have failed in that case and not attach a miibus(4) instance. - Convert the mebers of the MII data structure to unsigned where appropriate. This is partly inspired by NetBSD/OpenBSD. - Add MIIF_NOMANPAUSE and mii_phy_flowstatus() calls to drivers that weren't explicitly converted to support flow control before. It's unclear whether flow control actually works with these but typically it should and their net behavior should be more correct with these changes in place than without if the MAC driver sets MIIF_DOPAUSE.

| | | | | | | | | | Converted the remainder of the NIC drivers to use the mii_attach() introduced in r213878 (MFC'ed to stable/7 in r214685) instead of mii_phy_probe(). Unlike r213893 (MFC'ed to stable/7 in r214910) these are mostly straight forward conversions though. Notes: svn path=/stable/7/; revision=214925

* Big polling(4) cleanup.Gleb Smirnoff2005-10-011-44/+45
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | 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 Notes: svn path=/head/; revision=150789

| | | | | | | | | | | | | | | | | 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.

* Stop embedding struct ifnet at the top of driver softcs. Instead theBrooks Davis2005-06-102-15/+24
| | | | | | | | | | | | | | | | | | | | | | | 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.
