than a max size Ethernet frame without getting a frame-too-long error. VPC
seems to be adding 4 zeros at the end of every frame. Detect this condition
and simply truncate the packet to a max size Ethernet frame.
I now have no problems with networking on NetBSD inside Virtual PC 6.
Do a little mbuf rework while here. Change all uses of MGET*(*, M_WAIT, *)
to m_get*(M_WAIT, *). These are not performance critical and making them
call m_get saves considerable space. Add m_clget analogue of MCLGET and
make corresponding change for M_WAIT uses.
Modify netinet, gem, fxp, tulip, nfs to support MBUFTRACE.
Begin to change netstat to use sysctl.
- 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
particular, make sure that all the SIASTAT_ANS bits are in the right state
so we don't do something inane.
Still doesn't actually bring the link up properly, but at least it negotiates
most of the time, and does it a little faster.
1) Do not call tlp_sia_update_link() in Nway mode, and do not look at SIASTAT
in any other place that nway_status(), where we first check that it's valid.
In other places, look at IFM_ACTIVE after having call nway_status().
2) Eliminate stupid MII_MEDIACHG calls, and arrange for nway_service() to
update status on every call.
3) Nuke the synchronous case of nway_auto() from orbit.
4) Do not call nway_statchg() when using manual configuration; tlp_sia_set()
does everything we need.
1) Set OPMODE_TTM in the default tsti_opmode, so that nway_status doesn't
blow up and report the wrong media type when statically configured. (This
code is a hack.)
2) Do not set IFM_ACTIVE (i.e. ignore SIASTAT_LS*) when in auto-negotiation
mode and negotiation has not completed (per 21143 manual).
3) Do not clear auto-negotiation mode; otherwise the chip will not
renegotiate on a link failure.
With these changes, 10/100 selection is more stable, and auto-negotiation
comes up with the right status and detects link, but the link does not work
unless it's hardwired. More work is needed.
the interface was wired to full-duplex mode. Duh.
Also, add OPMODE_TTM to OPMODE_MEDIA_BITS, to insure that it is changed when
we switch between 10 and 100.
use "cp" instead of "ncp" as a temporary pointer into the SROM.
we still need the value of ncp here, it points to the next media block.
(update the copy of this code in tlp_21142_reset() just 'cause.)
this makes the BNC port on the Adaptec ANA-6911A work.
