[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index]

 



From: Stefan Wahren <stefan.wahren@xxxxxxxx>

This patch has been added to the 4.1 stable tree. If you have any
objections, please let us know.

===============

[ Upstream commit a4690afeb0d2d7ba4d60dfa98a89f3bb1ce60ecd ]

ether_setup sets IFF_TX_SKB_SHARING but this is not supported by
qca_spi as it modifies the skb on xmit.
