ATA over Ethernet driver 57 (For Linux 2.6 branch)
This driver allows the Linux kernel to use the ATA over Ethernet (AoE) network protocol. Using AoE, a Linux system can use AoE block devices like EtherDrive (R) storage blades. The block devices appear as local device nodes (e.g. /dev/etherd/e0.0). License: GNU General Public License (GPL) Changes:
The size of the data payload in each AoE packet is now exported for each AoE target. Various code cleanups were performed to bring the driver closer to the kernel.org driver.Image

hv_ata_pci_disengage

HYPER-V(4)						   BSD Kernel Interfaces Manual 						HYPER-V(4)

NAME

     hv_ata_pci_disengage -- Hyper-V ATA PCI Disengage driver

SYNOPSIS

     To compile this driver into the kernel, place the following lines in the system kernel configuration file:

	   device hyperv

DESCRIPTION

     The hv_ata_pci_disengage driver prevents the native FreeBSD ATA driver from loading in the presence of Hyper-V.  FreeBSD guests running on
     Hyper-V can take advantage of the Hyper-V Storage Virtual Consumer (hv_storvsc(4)) for using their IDE devices.  Since the ATA driver serves
     IDE devices as well, there is a chance that the ATA driver may interfere with the operations of hv_storvsc(4).  The hv_ata_pci_disengage
     driver avoids conflicts between the ATA driver and hv_storvsc(4) by disabling the ATA driver when the FreeBSD guest is booting.

     A side effect of disabling the ATA driver is that CDROM may become inoperational on FreeBSD guest partitions.  If CDROM access is a must then
     users may use "set hw.ata.disk_enable=1" at boot time to prevent the ATA driver from being disabled.

HISTORY

     Support for hv_ata_pci_disengage first appeared in FreeBSD 10.0.  The driver was developed through a joint effort between Citrix Incorpo-
     rated, Microsoft Corporation, and Network Appliance Incorporated.

AUTHORS

     FreeBSD support for hv_ata_pci_disengage was first added by Microsoft BSD Integration Services Team <bsdic@microsoft.com>.
