Subject: [PATCH 4.4 030/137] net: qca_spi: clear IFF_TX_SKB_SHARING

4.4-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Stefan Wahren <stefan.wahren@...e.com>

[ 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.
