Light syncmode support

[MrNaif2018]

Hello! There are already some issues on that topic, but I wanted to re-ask because those seem to got lost. Is it possible to run binance smart chain via

./geth_linux --config mainnet.toml --datadir data --syncmode light?

I've seen light syncmode working sometimes, but looks like since some time for me and others it doesn't find any peers. Also related: #702

hi, @MrNaif2018 since a lot of nodes running in fastnode mode which can not serve light client, I think it is difficulty to find a peer to serve light client.

I see, thanks. So it is not a bug? Because many users in the linked issue have told that it happened after geth update but I think it was not the one with fastsync
