Subject: linux-next: manual merge of the wireless-next tree with the net
 tree

Hi John,

Today's linux-next merge of the wireless-next tree got a conflict in
drivers/net/wireless/iwlwifi/pcie/trans.c between commit d012d04e4d63
("iwlwifi: disable the buggy chain extension feature in HW") from the net
tree and commit 4beaf6c2f8af ("iwlwifi: s/txq_setup/txq_enable") from the
wireless-next tree.

I fixed it up (I think - see below) and can carry the fix as necessary.

Cheers,
