Hi,

In preparing OpenWrt support for the TP-Link OnHub, I've extracted its
BDF for inclusion in the mainline board-2.bin.

Per the wiki [1]:

 * description for what hardware this is

   - IPQ8064-based router, with three radios -- a 2.4 GHz, a 5 GHz, and
     an auxiliary (monitoring?) radio
   - There are two variants of the OnHub: one by TP-Link, and one by
     ASUS. The TP-Link version of the OnHub [2] was released first, and
     the ASUS variant (ASUS OnHub SRT-AC1900) seems to use the same BDF.
     I use the first product when choosing the variant name.

 * origin of the board file (did you create it yourself or where you
   downloaded)

   - Pulled from the factory device filesystem for TP-Link OnHub, and
     compared with the ASUS filesystem.

 * ids to be used with the board file (ATH10K_BD_IE_BOARD_NAME in ath10k) +
   md5sum of each new board file to add

   - QCA988X hw2.0

     BoardNames[0]: 'bus=pci,vendor=168c,device=003c,subsystem-vendor=0000,subsystem-device=0000,variant=tplink,onhub'
     BoardMD5[0]: ab36ef267d15cfc02317ceeb38e8f548

Attached filename matches the ID above, with a '.bin' suffix appended.

Regards,
Brian
