The subcmds listed here in this new vendor NL80211 header file are used for
triggering a vendor specific configurations/implementations in the WLAN
driver/firmware layers for the Infineon chips which wouldn't be suitable
to add into the standard NL80211 header.

For Example, "IFX_VENDOR_SCMD_FRAMEBURST" is a proprietary feature which is
supported by the Infineon vendor hardware & software.
