Ok, like discussed in thread "linux-next: manual merge of the
wireless-drivers-next tree with the net-next tree" there seems to be a
problem on net-next in function iwl_mvm_set_tx_cmd(). Here is how I
propose to fix this.

When pulling the tag above you should get a conflict like this:

        tx_cmd->tx_flags = cpu_to_le32(tx_flags);
        /* Total # bytes to be transmitted */
        tx_cmd->len = cpu_to_le16((u16)skb->len +

        tx_cmd->life_time = cpu_to_le32(TX_CMD_LIFE_TIME_INFINITE);
        tx_cmd->sta_id = sta_id;

Pick the latter with skb_info and then add skb_info to the beginning of
the same function. So the function should be:

void iwl_mvm_set_tx_cmd(struct iwl_mvm *mvm, struct sk_buff *skb,
			struct iwl_tx_cmd *tx_cmd,
			struct ieee80211_tx_info *info, u8 sta_id)
{
	struct ieee80211_tx_info *skb_info = IEEE80211_SKB_CB(skb);
	struct ieee80211_hdr *hdr = (void *)skb->data;
	__le16 fc = hdr->frame_control;
	u32 tx_flags = le32_to_cpu(tx_cmd->tx_flags);
	u32 len = skb->len + FCS_LEN;
	u8 ac;

[...]

	tx_cmd->tx_flags = cpu_to_le32(tx_flags);
	/* Total # bytes to be transmitted */
	tx_cmd->len = cpu_to_le16((u16)skb->len +
		(uintptr_t)skb_info->driver_data[0]);
	tx_cmd->life_time = cpu_to_le32(TX_CMD_LIFE_TIME_INFINITE);
	tx_cmd->sta_id = sta_id;

Sorry about the hassle and please let me know if you have any problems.
Adding Luca and Emmanuel just in case I missed something.
