[][openwrt][mt7988][tops][TOPS Alpha release]
[Description]
Add alpha version of TOPS(tunnel offload processor system) and tops-tool
package.
TOPS package supports tunnel protocol HW offload. The support offload
tunnel protocols for Alpha version are L2oGRE and L2TPv2.
Notice that, TOPS only guarantees that inner packets are TCP. It is still
unstable for UDP inner packet flow.
tops-tool package provides several debug features such as logger, coredump
for TOPS.
