comments from vnode_pager_setsize(). This call was introduced in
revision 1.140 to address a problem that no longer exists.
Specifically, pmap_zero_page_area() has replaced a (possibly)
problematic implementation of page zeroing that was based on
vm_pager_map(), bzero(), and vm_pager_unmap().
while the global callout spinlock is not held, and can lead to PF#.

The lookup hurts a bit for connections but had been there anyway
if IPSEC was compiled in. So moving the lookup up a bit gives us
TSO support at not extra cost.

include the ithread scheduling step. Without this, a preemption might
occur in between the interrupt getting masked and the ithread getting
scheduled. Since the interrupt handler runs in the context of curthread,
the scheudler might see it as having a such a low priority on a busy system
that it doesn't get to run for a _long_ time, leaving the interrupt stranded
in a disabled state. The only way that the preemption can happen is by
a fast/filter handler triggering a schduling event earlier in the handler,
so this problem can only happen for cases where an interrupt is being
shared by both a fast/filter handler and an ithread handler. Unfortunately,
it seems to be common for this sharing to happen with network and USB
devices, for example. This fixes many of the mysterious TCP session
timeouts and NIC watchdogs that were being reported. Many thanks to Sam
Lefler for getting to the bottom of this problem.

only at address 0 which is supposed to be the only valid phy address
on Marvell PHY. The more correct solution would be masking PHY
address ranges allowable in PHY probe routine. Unfortunately,
FreeBSD has no way to retrict the PHY address ranges or to pass special
flags to PHY driver.
This change assumes that PHY hardwares attached to msk(4) would be
Marvell made 88E11xx PHY.
With this changes the phantom phys attached on 88E8036(Yukon FE)
should disappear.

publicly available datasheet for Yukon II and don't know what
bug/workaround exist for the specific hardware revision. Also I don't
think the vendor will release hardware errata in near future.
The hardware feature lists were not used at all except setting water
mark registers. Since msk(4) should know exact chip model/revision
number to decide which hardware capability could be used the extra
feature lists were redundant.
o Enable jumbo frame support for EC Ultra and disable jumbo frame

o Enable store and forward mode for standard MTU sized frame.
o Enable TSO for EC Ultra. However TSO/checksum offload is disabled
for jumbo frame case. Because EC Ultra can't use store and forward
mode for jumbo frame TSO/checksum offload is not available.
o Adjust Tx GMAC almost empty threshold value and add a jumbo frame

driver.
o Fix EC Ultra chip revision number.
rwlocks in conjuction with callouts. The function does basically what
callout_init_mtx() alredy does with the difference of using a rwlock
as extra argument.
CALLOUT_SHAREDLOCK flag can be used, now, in order to acquire the lock only
in read mode when running the callout handler. It has no effects when used
in conjuction with mtx.
In order to implement this, underlying callout functions have been made
completely lock type-unaware, so accordingly with this, sysctl
debug.to_avg_mtxcalls is now changed in the generic
debug.to_avg_lockcalls.
Note: currently the allowed lock classes are mutexes and rwlocks because
callout handlers run in softclock swi, so they cannot sleep and they
cannot acquire sleepable locks like sx or lockmgr.
