Yeah, I guess in net-next.git Dave assumed that 'info == skb_info' is
always valid in iwl_mvm_set_tx_cmd(), but I don't that's the case. So I
think the end case, after a merge, should look like this:
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;
I'm going to propose this to Dave in my pending pull request[1]. But I
would appreciate if someone else would double check this.
