Small formatting issue in nss-ifb README.md

[anonymous-one]

Thank you for the awesome build!

I only mention this because its super minor and 5 seconds to fix:

There is a small formatting issue in:

https://github.com/bitthief/nss-packages/blob/main/qca/nss-ifb/README.md

The tc commands, for those who are pretty novice at this, its unclear that there are in fact two commands in each direction.

I was copy pasting and tc would complain...

Essentially:

tc qdisc add dev nssifb root handle 1: nsstbl rate 500Mbit burst 1Mb tc qdisc add dev nssifb parent 1: handle 10: nssfq_codel limit 10240 flows 1024 quantum 1514 target 5ms interval 100ms set_default

Should be:

tc qdisc add dev nssifb root handle 1: nsstbl rate 500Mbit burst 1Mb
tc qdisc add dev nssifb parent 1: handle 10: nssfq_codel limit 10240 flows 1024 quantum 1514 target 5ms interval 100ms set_default

Same with the egress.

Thanks!
