MT7621A/S rev 0103 work perfectly with TSOv4/TSOv6. 

All fixes from SDK4320 already included.

MT7621A/S rev0103, QDMA port with TSO is 100% works. 

Tested 3 hours + hard case: transmission to cifs share.

QDMA tx_ring txd_info4 dump look like 0xf2000000, TSO bit is set.

MT7620 rev < 0205 has bug with TSO, Frame Engine really hungs (after 1-3 min on 
SMB/FTP copy). Not CPU. After reset FE via reg 0x34, FE works again.

To more complexity testing, I need sample MT7621 with USB3. Now I used Buffalo 
WSR-1166DHP, this is fairy router on MT7621A + DDR3, but not have USB ports. 

Early, I worked with R6220 (and full adapted this firmware, only Uboot replace 
needed), but I already gave back R6220 to owner.
