Includes drivers for I2C, I2S, PCMCIA controller, USB device controller,
OHCI USB controller (from OpenBSD) and some improvements to the LCD
controller driver.
Commons up the code for reading files and buffers, and allows a further
change where we don't copy the data out of the buffer when generating 'lines.
This will speed up makefile parsing (esp .if clauses).
- clear re_vlanctl in DMA descriptors before starting TX and RX
to avoid stale tags
- use bswap16() rather than be16toh() or htons() on VLAN tag access
since we already use htole32()
Closes PR kern/32643 and also fixes HW VLAN tagging on big endian machines.
rtcache_init and rtcache_init_noclone lookup ro_dst and store
the result in ro_rt, taking care of the reference counting and
calling the domain specific route cache.
rtcache_free checks if a route was cashed and frees the reference.
rtcache_copy copies ro_dst of the given struct route, checking that
enough space is available and incrementing the reference count of the
cached rtentry if necessary.
rtcache_check validates that the cached route is still up. If it isn't,
it tries to look it up again. Afterwards ro_rt is either a valid again
or NULL.
rtcache_copy is used internally.
Adjust to callers of rtalloc/rtflush in the tree to check the sanity of
ro_dst first (if necessary). If it doesn't fit the expectations, free
the cache, otherwise check if the cached route is still valid. After
that combination, a single check for ro_rt == NULL is enough to decide
whether a new lookup needs to be done with a different ro_dst.
Make the route checking in gre stricter by repeating the loop check
after revalidation.
Remove some unused RADIX_MPATH code in in6_src.c. The logic is slightly
changed here to first validate the route and check RTF_GATEWAY
afterwards. This is sementically equivalent though.
etherip doesn't need sc_route_expire similiar to the gif changes from
dyoung@ earlier.
Based on the earlier patch from dyoung@, reviewed and discussed with
him.
1) When detaching, don't try to close things we shouldn't (after
doing the header). Specifically, mip->mi_head_end was not
getting set correctly in mime_sendmessage().
2) Change paging to be closer to its old behavior: next, dt, and dp
should only page if the crt variable is set; and don't automatically
page most other commands - the user can always pipe them into more.
