Larry, I CC-ed you because I noticed in an earlier message on the lwn
mailing list that you own (or used to own) the exact model of BCM4321
as the one I have now:
0c:00.0 Network controller [0280]: Broadcom Corporation BCM4321
802.11a/b/g/n [14e4:4328] (rev 03)
Subsystem: Hewlett-Packard Company BCM4321 802.11a/b/g/n
Wireless LAN Controller [103c:1367]
Can anybody with a BCM4321 send me a full SPROM dump from their card
(preferably a HP BCM4321, but I guess any would do)? I want to hack
something up and try fix my card.
Octavian,
I do have a BCM4321 (14e4:4328) that works with the latest b43. I'm using
508.154 firmware.
Performance is not great, but it is adequate. The TX and RX rates (Mbps) for 3
common netperf tests are as follows:
TCP_MAERTS TX Test: 7.68 7.75 7.76 8.42 7.12 6.69 6.61 6.65 7.99 7.15
TCP_MAERTS RX Test: 9.50 12.15 10.70 8.78 11.55 11.32 11.97 9.71 6.00 9.17
Results: TX: max 8.42, min 6.61. Mean 7.38(0.60)
RX: max 12.15, min 6.00. Mean 10.09(1.78)
TCP_STREAM TX Test: 9.72 9.18 6.54 9.49 9.56 9.02 9.31 9.16 9.49 10.55
TCP_STREAM RX Test: 4.39 5.68 2.91 7.76 7.07 7.65 6.92 7.50 7.48 7.59
Results: TX: max 10.55, min 6.54. Mean 9.20(0.98)
RX: max 7.76, min 2.91. Mean 6.50(1.57)
TCP_SENDFILE TX Test: 13.54 14.21 11.01 6.74 11.55 10.25 9.99 9.87 11.30 12.38
TCP_SENDFILE RX Test: 7.06 7.03 7.03 7.06 6.90 7.10 7.15 6.84 7.07 6.84
Results: TX: max 14.21, min 6.74. Mean 11.08(2.00)
RX: max 7.15, min 6.84. Mean 7.01(0.10)
The netperf server for TX and transmitter for the RX tests is attached to my
AP/router/switch via a 100 Mbps wired connection.

My MAC address is 00:1A:73:65:94:D0. You should have the MAC for your device
written on the label. In any case, do not use the same one as in my device.
