ALT_BREAK_TO_DEBUGGER. In addition to "Enter ~ ctrl-B" (to enter the
debugger), there is now "Enter ~ ctrl-P" (force panic) and
"Enter ~ ctrl-R" (request clean reboot, ala ctrl-alt-del on syscons).
We've used variations of this at work. The force panic sequence is
best used with KDB_UNATTENDED for when you just want it to dump and
get on with it.
The reboot request is a safer way of getting into single user than
a power cycle. eg: you've hosed the ability to log in (pam, rtld, etc).
It gives init the reboot signal, which causes an orderly reboot.
I've taken my best guess at what the !x86 and non-sio code changes
should be.
This also makes sio release its spinlock before calling KDB/DDB.
- Limit grabbing the lock to SIOCSIFFLAGS.
- Move ieee80211_start_all() to SIOCSIFFLAGS.
- Remove SIOCSIFMEDIA as it is not useful.
- Limit ether_ioctl to only SIOCGIFADDR. SIOCSIFADDR and SIOCSIFMTU have no
affect as there is no input/output path in the vap parent. The vap code
will handle the reinit of the mac address changes.
- Split off ndis_ioctl_80211 as it was getting too different to wired devices.
This fixes a copyout while locked and a lock recursion.

total of 6 interrupt resources for scc(4) on macio(4). This
is 3 per channel, of which the 1st of each channel is the
interrupt associated with the SCC. The other 2 are for DMA
operation.
Change scc_bfe_attach() to accept an argument that's the
number of interrupts per channel (ipc) and change each bus
front-end (bfe) to pass that argument through a wrapper
for the device_attach method.
For now, we only allocate the 1st interrupt of each channel
to perserve behaviour.

PR 122839 is fixed in both em and in igb
Second, the issue on building modules since the static kernel
build changes is now resolved. I was not able to get the fancier
directory hierarchy working, but this works, both em and igb
build as modules now.
Third, there is now support in em for two new NICs, Hartwell
(or 82574) is a low cost PCIE dual port adapter that has MSIX,
for this release it uses 3 vectors only, RX, TX, and LINK. In
the next release I will add a second TX and RX queue. Also, there
is support here for ICH10, the followon to ICH9. Both of these are
early releases, general availability will follow soon.
Fourth: On Hartwell and ICH10 we now have IEEE 1588 PTP support,
I have implemented this in a provisional way so that early adopters
may try and comment on the functionality. The IOCTL structure may
change. This feature is off by default, you need to edit the Makefile
and add the EM_TIMESYNC define to get the code.
Enjoy all!!

o Add CTASSERTs ensuring that HME_NRXDESC and HME_NTXDESC are set to
legal values.
o Use appropriate maxsize, nsegments and maxsegsize parameters when
creating DMA tags and correct some comments related to them.
o The FreeBSD bus_dmamap_sync(9) supports ored together flags for quite
some time now so collapse calls accordingly.
o Add missing BUS_DMASYNC_PREREAD when syncing the control DMA maps in
hme_rint() and hme_start_locked().
o Keep state of the link state and use it to enable or disable the MAC
in hme_mii_statchg() accordingly as well as to return early from
hme_start_locked() in case the link is down.
o Introduce a sc_flags and use it to replace individual members like
sc_pci.
o Add bus_barrier(9) calls to hme_mac_bitflip(), hme_mii_readreg(),
hme_mii_writereg() and hme_stop() to ensure the respective bit
has been written before we starting polling on it and for the right
bits to change.
o Rather just returning in case hme_mac_bitflip() fails and leaving us
in an undefined state report the problem and move on; chances are
the requested configuration will become active shortly after.
o Don't call hme_start_locked() in hme_init_locked() unconditionally
but only after calls to hme_init_locked() when it's appropriate, i.e.
in hme_watchdog().
o Add a KASSERT which asserts nsegs is valid also to hme_load_txmbuf().
o In hme_load_txmbuf():
- use a maximum of the newly introduced HME_NTXSEGS segments instead
of the incorrect HME_NTXQ, which reflects the maximum TX queue
length, for loading the mbufs and put the DMA segments back onto
the stack instead of the softc as 16 should be ok there.
- use the common errno(2) return values instead of homegrown ones,
- given that hme_load_txmbuf() is allowed to fail resulting in a
packet drop for quite some time now implement the functionality of
hme_txcksum() by means of m_pullup(9), which de-obfuscates the code
and allows to always retrieve the correct length of the IP header, [1]
- also add a KASSERT which asserts nsegs is valid,
- take advantage of m_collapse(9) instead of m_defrag(9) for
performance reasons.
o Don't bother to check whether the interface is running or whether its
queue is empty before calling hme_start_locked() in hme_tint(), the
former will check these anyway.
o In hme_intr() call hme_rint() before hme_tint() as gem_tint() may
take quite a while to return when it calls hme_start_locked().
o Get rid of sc_debug and just check if_flags for IFF_DEBUG directly.
o Add a shadow sc_ifflags so we don't reset the chip when unnecessary.
o Handle IFF_ALLMULTI correctly. [2]
o Use PCIR_BAR instead of a homegrown macro.
o Replace sc_enaddr[6] with sc_enaddr[ETHER_ADDR_LEN].
o Use the maximum of 256 TX descriptors for better performance as using
all of them has no additional static cost rather than using just half
of them.

in order to get rid of bus space handle and tag in struct sym_hcb.
- Remove unused members related to bus addresses in struct sym_hcb.
- sym(4) takes care of allocating an instance of struct sym_hcb
itself so don't let newbus allocate it as an unused softc also.
- Add basic MPSAFE locking. This includes changing the sym(4) CCBs
to be allocated up-front instead of on demand as needed. Besides
making these allocations more likely to succeed, this also solves
the problem of calling bus_dmamap_create(9) with the SIM mutex
held.

- Fix some spelling in comments.

Note this includes changes to all drivers and moves some device firmware
loading to use firmware(9) and a separate module (e.g. ral). Also there
no longer are separate wlan_scan* modules; this functionality is now
