Merge r207585 from cas(4):- Don't probe for PHYs if we already know to use a SERDES. Unlike as with cas(4) this only serves to speed up the the device attach though and can only be determined via the OFW device tree but not from the VPD.- Don't touch the MIF when using a SERDES.- Add some missing bus space barriers, mainly in the PCS code path.

- Initialize the ifnet structure, especially if_dname, before probing the PHYs as some PHY drivers use it (but probably shouldn't). How gem(4) has worked with brgphy(4) on powerpc without this so
- Initialize the ifnet structure, especially if_dname, before probing the PHYs as some PHY drivers use it (but probably shouldn't). How gem(4) has worked with brgphy(4) on powerpc without this so far is unclear to me.- Introduce a dying flag which is set during detach and checked in gem_ioctl() 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.- In gem_stop() reset rather than just disable the transmitter and receiver in order to ensure we're not unloading DMA maps still in use by the hardware. [1]- The blanking time is specified in PCI clocks so we should use twice the value when operating at 66MHz.- Spell some 2 as ETHER_ALIGN and a 19 as GEM_STATUS_TX_COMPLETION_SHFT to make the actual intentions clear.- As we don't unload the peak attempts counter ignore its overflow interrupts.- Remove a stale setting of a variable to GEM_TD_INTERRUPT_ME which isn't used afterwards.- For optimum performance increment the TX kick register in multiples of 4 if possible as suggested by the documentation.- Partially revert r164931; drivers should only clear the watchdog timer if all outstanding TX descriptors are done.- Fix some debugging strings.- Add a missing BUS_DMASYNC_POSTWRITE in gem_rint().- As the error paths in the interrupt handler are generally unlikely predict them as false.- Add support for the SBus version of the GEM controller. [2]- Add some lock assertions.- Improve some comments.- Fix some more or less cosmetic issues in the code of the PCI front-end.- Change some softc members to be unsigned where more appropriate and remove unused ones.Approved by: re (kib)Obtained from: NetBSD (partially) [2], OpenBSD [1]MFC after: 2 weeks
