Hi Dmitry,
I wonder if modifying mib:ieee802154_dev_set_channel() to push the
channel down to the hardware is acceptable?
void ieee802154_dev_set_channel(struct net_device *dev, u8 val)
{
struct ieee802154_sub_if_data *priv = netdev_priv(dev);
int res;
BUG_ON(dev->type != ARPHRD_IEEE802154);
write_lock_bh(&priv->mib_lock);
priv->chan = val;
write_unlock_bh(&priv->mib_lock);
if (priv->hw->phy->current_channel != priv->chan) {
res = priv->hw->ops->set_channel(&priv->hw->phy->priv,
val);
if (res)
pr_debug("set_channel failed\n");
}
}
