ASUS PCE-AC68

Overview
This device is using a Broadcom BCM4360 (PCIe, 3x3 802.11b/g/n/ac)
 * for maximum PHY rates of 1.3Gbps on the 5GHz band (11ac) and
 * 600Mbps on the 2.4GHz band (11n w/ QAM256 [TurboQAM]).

It would appear (from the photos provided to the FCC and those provided
 * directly from ASUS) that this device is identical to the ASUS PCE-AC66.

See also ASUS PCE-AC88 AC3100 (PCIe, 4x4 802.11b/g/n/ac)..
 * In order to reach 600Mbps/2.4 GHz, RT-AC68U must connect
 * to the ASUS PCE-AC66/68 or RT-AC68U in media bridge mode.

Per ASUS's drivers, the PCI ID for the device is 14e4:43a0..
 * which seems to be the default 4360 ID.
