Increase the number of TX DMA segments from 32 to 35. It turned out 32 is not enough to support a full sized TSO packet. While I'm here fix a long standing bug introduced in r169632 in bce(4) where it didn't include L2 header length of TSO packet in the maximum DMA segment size calculation.

Perform media change after setting IFF_DRV_RUNNING flag. Without it, driver would ignore the first link state update if controller already established a link.

- Merge from r249476: Ensure that PCI bus BUS_GET_DMA_TAG() method sees the actual PCI device which makes the request for DMA tag, instead of some descendant of the PCI device, by creating a pass-through trampoline. - Sprinkle const on tables. - Use NULL instead of 0 for pointers. - Take advantage of nitems().

Mechanically substitute flags from historic mbuf allocator with malloc(9) flags in sys/dev.

RX checksum offloading on old Yukon controllers seem to cause more problems. Disable RX checksum offloading on controllers that don't use new descriptor format but give chance to enable it with ifconfig(8).

Increase wait time for OP_TCPSTART command processing. It seems 100us is not enough to ensure prefetch unit work.

Enable 64bit DMA addressing support for all msk(4) controllers. Unnecessarily complex LE format used on Marvell controller was main reason not to enable 64bit DMA addressing in driver. If high 32bit address of DMA address of TX/RX buffer is changed, driver has to generate a new LE. In TX path, driver will keep track of lastly used high 32bit address of DMA address and generate a new LE whenever it sees high address change in the DMA address. In RX path, driver will always use two LEs to specify 64bit DMA address of RX buffer. If the high 32bit address of DMA address of RX buffer is the same as previous DMA address of RX buffer, driver does not have to use two LEs but driver will use two LEs for simplicity in RX ring management. One of draw back for switching to 64bit DMA addressing is that the large amount of LEs are used to specify 64bit DMA address such that number of available LEs for TX/RX buffers are considerably reduced. To mitigate the issue, increase number of available LEs from 256 to 384 for TX and from 256 to 512 for RX. For 32bit architectures, msk(4) does not use 64bit DMA addressing to save resources.

Use DEVMETHOD_END to mark end of device methods. Remove superfluous device methods. Add some missing __FBSBID() macros.

Close a race where SIOCGIFMEDIA ioctl get inconsistent link status. Because driver is accessing a common MII structure in mii_pollstat(), updating user supplied structure should be done before dropping a driver lock. Reported by: Karim (fodillemlinkarimi <> gmail dot com)

Correctly check MAC running status before disabling TX/RX MACs.
