rG97c802923e20: if_ovpn: remove peer limit
Summary

Replace the fixed-sized array by an RB_TREE. This should both speed up
lookups and remove the 128 peer limit.

We may wish to consider adding additional trees to also speed up the
lookup by IPv4/IPv6 addresses.

(struct ovpn_kpeer *)&p

The cast looks redundant. p is declared as struct ovpn_kpeer at line 278

Looks good to me.

And you may also want to retire OVPN_MAX_PEERS ;)

Thanks. I spotted that one eventually and fixed it, but figured it wasn't worth updating the review for that.
