Do I need this kernel option http://i.imgur.com/gYfCDuv.png?

The symbol names are
CONFIG_MAC80211_RC_MINSTREL_HT
CONFIG_MAC80211_RC_MINSTREL

And help says: "This option enables the 'minstrel' TX rate control algorithm"

Could someone explain what this is, what the benefit of activating it, and how to find out if my hardware supports it?
Code:
# lspci -k -v -s 08:00.0

08:00.0 Network controller: Intel Corporation PRO/Wireless 3945ABG [Golan] Network Connection (rev 02)
        Subsystem: Hewlett-Packard Company PRO/Wireless 3945ABG [Golan] Network Connection
        Flags: bus master, fast devsel, latency 0, IRQ 16
        Memory at e8000000 (32-bit, non-prefetchable) [size=4K]
        Capabilities: [c8] Power Management version 2
        Capabilities: [d0] MSI: Enable- Count=1/1 Maskable- 64bit+
        Capabilities: [e0] Express Legacy Endpoint, MSI 00
        Kernel driver in use: iwl3945
        Kernel modules: iwl3945

charles ... its not hardware related, its an algorithm, and yes, you need it. Full details of Minstrel can be found on Linux Wireless.

Thanks for the link. Guess it's worth adding these to kernel options in https://wiki.gentoo.org/wiki/Wifi

charles ... you're welcome. I'm fairly sure these are enabled automatically once MAC80211 is ... they may even be enabled as defconfig.
