a series of Y2k-compliant multiplexed-bus RTC chips. At the lowest levels,
the DS1687 and successors are register-compatible with the MC146818(A) and
DS1287, but also provide Y2k-safe date storage and other extra bits, like a
silicon serial number and larger amounts of NVRAM.
which is safer than the loop there used to be here.
wi_mwrite_bap: if wi_write_bap fails, don't keep on going: this
way you avoid writing garbage to the radio. First time you see
an odd-length mbuf, copy the remainder of the chain to sc_txbuf
and from there to the MAC. This way, you do not read an mbuf past
the end of its data (occasionally you will cross a page doing
that!) and you avoid expensive, excess seeks in the radio's own
buffer chain.
wi_rx_intr: clamp the frame length told to us by the driver to the
most bytes we can fit in our mbuf cluster.
I am still getting e-mails from my testers telling me how much
better this makes things.
LINK_STAT notification for every change of BSSID, so the firmware's
BSSID and the driver's BSSID will get out of sync. This has two
bad affects. First, because the 802.11 framework filters received
packets based on BSSID, many packets can be dropped before the
driver adopts the firmware's BSSID. Second, ifconfig's tells a
misleading BSSID to the operator.
This problem is most apparent in networks where every station does
not hear every other. I reproduce these conditions in an office by
removing/replacing the antennas on my 802.11 cards.
As a solution, in IBSS mode, the driver will ask the firmware for
the BSSID every five seconds. Also, whenever the driver receives
a frame carrying a different BSSID than the driver's BSSID, then
the driver asks the firmware for the BSSID before handing the frame
to ieee80211_input.
the MIF Configuration Register PHY_Select, there is no use in pretending
we could talk to both at the MII interface layer.
If both PHY are reported to be present, prefer the external one.
Remember this selection and enforce it in hme_mii_{read,write}reg.
This fixes problems with one of the dual hmes in Netra T1s.
