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.

Pertinent data from the dmesg output:

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.
