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.

- 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.

Fix build breakage introducted in r213604.

Remove unnecessary controller reinitialization. StarFire controller does not require controller reinitialization to program perfect filters. While here, make driver immediately exit from interrupt/polling handler if driver reinitialized controller. PR: kern/87506

if_ioctl, if_watchdog, etc, or in functions that are used by these methods only. In all other cases use device_printf(). This also fixes several panics, when if_printf() is called before softc->ifp was initialized. Submitted by: Alex Lyashkov
