net: dsa: tag_ksz: linearize SKB before adding DSA tag
requested to merge github/fork/linosanfilippo-kunbus/fix/REVPI-1381/linearize_skbs into devel/revpi-5.10
Created by: linosanfilippo-kunbus
In ksz9477_xmit() skb_put() is used to add the DSA tag to the passed SKB. However skb_put() must only be called for linear SKBs which may not be the case if the DSA slave device inherited NETIF_F_SG from the master device. So make sure the SKB is always linearized.
