    System Environment:
    Mini PCIe slot - Intel dual band wireless-AC 7260
    ubuntu 12.4
    Linux 3.8 kernel version

    Bringup:
    1. Inserted the Intel dual band wireless-AC 7260 in the Mini PCIe slot in the board.
    2. Checked for the Intel dual band wireless-AC 7260 PCIe devices through "lspci" command - not detected

    I have the following queries
    Ø Why the wireless-AC 7260 will not list in the PCIe tree ?
    Ø I need the sequence of detecting/enumeration for this card and how to verify my card is present or not?
    Ø Is ucode is require for the PCIe enumeration?

    The 3.8 kernel does not support the 7260. The minimum kernel is 3.11. Though the latest kernels provide more support....Also the latest firmware blob (UCODE) is included in linux-firmware: https://git.kernel.org/cgit/linux/kernel/git/firmware/linux-firmware.git/tree/
    Code:
    *-network             
           description: Wireless interface
           product: Wireless 7260
           vendor: Intel Corporation
           physical id: 0
           bus info: pci@0000:0a:00.0
           logical name: wlp10s0
           version: 63

           clock: 33MHz
           capabilities: bus_master cap_list ethernet physical wireless
           configuration: broadcast=yes driver=iwlwifi driverversion=3.13.6-1-ARCH firmware=22.15.8.0 ip=STUFF-GOES-HERE latency=0 link=yes multicast=yes wireless=IEEE 802.11abgn
           resources: irq:45 memory:74500000-74501fff
    NOTE* It seems that 3.14 will finally provide AC support.
