In this mode, the PPP packets start with the protocol identifier and don't
have any explicit framing (which may be added by the lower level driver).
Make input/output statistics a little bit more correct by adding a hardware
driver adjustable framing length for each packet (instead of the constant
value "3" used before).
While there, bump authentication name length from 32 to 48 (I have a
connection where I need more than 32). XXX - this should not be artificialy
limited at all.
tree, which allows a packet with Ethernet headers already present to
run through the ALTQ packet classifier. This is needed in order to
suport ALTQ on VLAN and bridge devices.
adds rt_parent to link parent from child (like NRL did, ours do refcnt
rt_refcnt properly).
bsdi rt_walkbranch would speedup the processing, but since the code will not
be visited too frequently, the current code (with rt_walktree) should be okay.
let static routes overwrite cloned routes, as cloned routes can come back again
if necessary. behavior same as freebsd/bsdi, code partially from bsdi42.
(NRL rt->rt_parent was not added)
should fix PR 11916 and maybe some other PRs with ARP behavior.
recompilation of usr.sbin/route6d is suggested.
have sys/net/route.c:rtrequest1(), which takes rt_addrinfo * as the argument.
pass rt_addrinfo all the way down to rtrequest, and ifa->ifa_rtrequest.
3rd arg of ifa->ifa_rtrequest is now rt_addrinfo * instead of sockaddr *
(almost noone is using it anyways).
benefit: the follwoing command now works. previously we need two route(8)
invocations, "add" then "change".
# route add -inet6 default ::1 -ifp gif0
remove unsafe typecast in rtrequest(), from rtentry * to sockaddr *. it was
introduced by 4.3BSD-reno and never corrected.
XXX is eon_rtrequest() change correct regarding to 3rd arg?
eon_rtrequest() and rtrequest() were incorrect since 4.3BSD-reno,
so i do not have correct answer in the source code.
someone with more clue about netiso-over-ip, please help.
the link level name for the interface (ifp->if_sadl) is allocated
before ifp->if_addrlen is initialized, which could lead to allocating
too little space for the link level address.
Do this by splitting allocation of the link level name out of
if_attach() and into if_alloc_sadl(), which is normally called
by functions like ether_ifattach(). Network interfaces which
don't have a link-specific attach routine must call if_alloc_sadl()
themselves (example: gif).
Link level names are freed by if_free_sadl(), which can be called
from e.g. ether_ifdetach(). Drivers never need call if_free_sadl()
themselves as if_detach() will do it if it is not already done.
While here, add the ability to pass an AF_LINK address to
SIOCSIFADDR in ether_ioctl() (this is what caused me to notice
the problem that the above fixes).
Defer output processing to the software interrupt.
Note, that in the process of doing this, I discovered several
very broken things about this driver, which are not fixed with
this commit. It should work as well as it previously did, but
this code could be seriously improved. As soon as I can find
my second Metricom radio, I'll give it a proper shakedown.
Once we have a complete frame, schedule a STRIP software interrupt,
and manipulate ipintrq from there. This will allow us to clean up
the use of splimp() in this file later.
