- implement SIMPLEQ_REMOVE(head, elm, type, field). whilst it's O(n),
this mirrors the functionality of SLIST_REMOVE() (the other
singly-linked list type) and FreeBSD's STAILQ_REMOVE()
- remove the unnecessary elm arg from SIMPLEQ_REMOVE_HEAD().
this mirrors the functionality of SLIST_REMOVE_HEAD() (the other
singly-linked list type) and FreeBSD's STAILQ_REMOVE_HEAD()
- remove notes about SIMPLEQ not supporting arbitrary element removal
- use SIMPLEQ_FOREACH() instead of home-grown for loops
- use SIMPLEQ_EMPTY() appropriately
- use SIMPLEQ_*() instead of accessing sqh_first,sqh_last,sqe_next directly
- reorder manual page; be consistent about how the types are listed
- other minor cleanups
so that they're more useful for arbitrary types of external storage:
* Add an "mbuf *" argument to (*ext_free)(). If non-NULL, (*ext_free)()
is expected to free the mbuf itself. This allows (*ext_free)() to use
the mbuf for bookkeeping (e.g. deferring the work to a helper thread).
If the "mbuf *" argument is NULL, we are assumed to be in a context
which is safe for performing the destructor operation *now*.
* Adjust MEXTREMOVE() and MFREE() routines for above change.
* Update "ade" and "ti" drivers for new semantics.
network interfaces. This works by pre-computing the pseudo-header
checksum and caching it, delaying the actual checksum to ip_output()
if the hardware cannot perform the sum for us. In-bound checksums
can either be fully-checked by hardware, or summed up for final
verification by software. This method was modeled after how this
is done in FreeBSD, although the code is significantly different in
most places.
We don't delay checksums for IPv6/TCP, but we do take advantage of the
cached pseudo-header checksum.
Note: hardware-assisted checksumming defaults to "off". It is
enabled with ifconfig(8). See the manual page for details.
Implement hardware-assisted checksumming on the DP83820 Gigabit Ethernet,
3c90xB/3c90xC 10/100 Ethernet, and Alteon Tigon/Tigon2 Gigabit Ethernet.
if we are requested range of multicast address or too many multicast address,
program multicast filter to receive all multicast address. And set/clear
IFF_ALLMULTI flag properly.
pci_attach_args *" instead of from four separate parameters which in
all cases were extracted from the same "struct pci_attach_args".
This both simplifies the driver api, and allows for alternate PCI
interrupt mapping schemes, such as one using the tables described in
the Intel Multiprocessor Spec which describe interrupt wirings for
devices behind pci-pci bridges based on the device's location rather
the bridge's location.
Tested on alpha and i386; welcome to 1.5Q
1.39:
Have if_ti stop "hiding" the softc pointer in the buffer region. Rather,
use the available void * passed to the free routine and pass the softc
pointer through there.
1.33:
Add support for the Netgear GA620T copper gigabit card.
1.32:
Tweak probe message so that 1000baseSX and 1000baseT cards are
explicitly identified.
1.31:
Update the Tigon driver to support 1000baseTX gigE over copper AceNIC
cards. This basically involves switching to the 12.4.13 firmware, plus
a couple of minor tweaks to the driver.
NetBSD changes:
get rid of ti_inuse, the mbuf ref counting code should call ti_free() when
needed.
Use hardware 802.1q support.
- fix a bug in ti_encap() where a NULL pointer could be used if we run out
of tx descriptors (return ENOMEM instead, and let the caller assert OACTIVE)
- sync boot messages with NetBSD's pci standart (print ti_name and irq
line)
- add a shutdown hook to stop the board, so that the board will not DMA at
random places while we're rebooting
- convert all but TIGON 1 transmit descriptors to use bus_space
(this last one isn't trivial to get rigth and I don't have the hardware to
test)
- If we can't map the mem space linar, retry to map it nolinear. Punt if
we couldn't map the mem space linear and we found a Tigon 1 chip.
With these changes a Tigon 2 board (netgear BA620 at last) can be used in
my DS20.
