MFC r222219,222221,222223,222226-222227,222231,222516:
Merge all relevant changes from HEAD to fix long standing
instability issues of msk(4). To get desired effect of this
merge, cold restarting is required because incorrectly programmed
registers are not reset to default value.
PR: kern/114631, kern/116853, kern/139093, kern/144206,
kern/147824, kern/151169, kern/154591, kern/155636,
kern/156493
r222219:
Do not blindly clear entire GPHY control register. It seems some
bits of the register is used for other purposes such that clearing
these bits resulted in unexpected results such as corrupted RX
frames or missing LE status updates. For old controllers like
Yukon EC it had no effect but it caused all kind of troubles on
Yukon Supreme.
This change shall improve stability of controllers like Yukon
Ultra, Ultra2, Extreme, Optima and Supreme.
r222221:
Rework store and forward configuration of TX MAC FIFO. Basically it
enables store and forward mode except for jumbo frame on Yukon
Ultra.
r222223:
Do not configure RAM registers for controllers that do not have
them. These registers are defined only for Yukon XL, Yukon EC and
Yukon FE.
r222226:
Make sure to enable all clocks before accessing registers.
Releasing PHY from power down/COMA is done after enabling all
clocks. While I'm here remove unnecessary controller reset.
r222227:
Do not touch ASF related register for controllers that do not have
these registers. Also disable Watchdog of ASF microcontroller.
r222231:
When MTU is changed, check whether driver should be reinitialized or
not. If reinitialized is required, clear driver running flag.
r222516:
Correctly check MAC running status before disabling TX/RX MACs.
