Dear Arend, as followup to my last inquiry, since it's passed more than 2 weeks, I'm afraid I didn't receive any answer. As from subject, I finally discovered that brcmsmac is not compliant to 802.11 regulations for BCM4313. So, as purchasing customer, and member of Linux users community, I try to propose my questions to you again now, 3 in total: 1) Regulatory domain - you wrote "brcmsmac does assure tx power is within regulatory limits by enforcing a world regulatory domain" That affirmation is *FALSE*. I spent the whole weekend putting brcmsmac under heavy trace, all functions, above all the phy ones. Some code "supposes" to enforce a regulatory domain, but the effect is total null. I tried recompile the regulatory domain database, those functions did not retrieve the new values. Whatever values I set for domain 00, the effect was null - BCM4313 kept functioning independently. The functions, phy and not, which are "supposed" to set the eeprom registries for regdomain enforce, have effect null - the BCM4313 kept functioning independently. I tried setting random numbers in those functions and registries, the effect was null - the BCM4313 kept functioning independently. At the edge of my frustration, I started commenting away from the code those whole phy functions, the effect was null again - the BCM4313 kept functioning independently. I don't know for what Broadcom hw device were written and *tested* those functions - but sure is, they do *NOT* work for BCM4313. Could you please explain how/where the BCM4313 is supposed to "enforcing a world regulatory domain" ? 2) MCS - 11n modulated frames are not detected in BCM4313 monitor mode - I informed you about this issue more than 1 year ago, and again 2 weeks ago. The issue still reproduces, and no sign of any fix. When/in what backports version, this issue is supposed to be fixed finally? 3) I explicitly purchased this BCM4313 already 1 year ago, with the following specs: 0x4313 rev 0x01 package 0x08, 3 cores ChipCommon, IEEE802.11 and PCIe. I have been searching for any technical datasheet specification document about BCM4313 on Broadcom website and others. Did not find any. Could you please send me a detailed technical datasheet specification document about BCM4313, for programming/dev purposes?
