wireguard: sending the first handshake
After creating a peer, we send a handshake request. But it's not quite right to call wg_send_keepalive() directly. According to documentation, handshake initiation is sent after (REKEY_TIMEOUT + jitter) ms. Since it's the first one - we don't need to take REKEY_TIMEOUT into account, but we still have jitter. It also makes no sense to immediately send keepalives, because the connection is not created yet. Type: fix Signed-off-by: Artem Glazychev <artem.glazychev@xored.com> Change-Id: I61707e4be79be65abc3396b5f1dbd48ecbf7ba60
