Wed May 18 11:51:25 2016 -0700 iwlwifi: fix mis-merge that breaks the driver My laptop that uses the intel 7680 iwlwifi module would no longer connects to the network. It would fail with a "Microcode SW error detected." and spew out register state over and over again without ever connecting to the network. The cause is mis-merge in commit 909b27f70643, where David seems to have lost some of the changes to iwl_mvm_set_tx_cmd() from commit 5c08b0f5026f ("iwlwifi: mvm: don't override the rate with the AMSDU len"). The reason seems to be a conflict with commit d8fe484470dd ("iwlwifi: mvm: add support for new TX CMD API"), which touched a line adjacent to the changes in 909b27f70643. David missed the fact that "info->driver_data[0]" had become "skb_info->driver_data[0]". Then he removed the skb_info because it was unused. This just re-updates iwl_mvm_set_tx_cmd() with the lost two lines.
