Author: markj Date: Mon Feb 17 22:40:05 2014 New Revision: 262137 URL: http://svnweb.freebsd.org/changeset/base/262137 Log: MFC r258036: Add IDs for the ASIX 88179 and 88178A USB to GigE adapters. MFC r258331: Import the axge(4) driver for the ASIX AX88178A and AX88179 USB Ethernet adapters. Both devices support Gigabit Ethernet and USB 2.0, and the AX88179 supports USB 3.0. MFC r258617 (by lwhsu): Also note to add xhci(4) to kernel configuration to utilize USB 3.0 MFC r258618 (by lwhsu): Mention axge(4) Added: stable/10/share/man/man4/axge.4 - copied, changed from r258331, head/share/man/man4/axge.4 stable/10/sys/dev/usb/net/if_axge.c - copied unchanged from r258331, head/sys/dev/usb/net/if_axge.c stable/10/sys/dev/usb/net/if_axgereg.h - copied unchanged from r258331, head/sys/dev/usb/net/if_axgereg.h stable/10/sys/modules/usb/axge/ - copied from r258331, head/sys/modules/usb/axge/ Modified: stable/10/share/man/man4/Makefile stable/10/share/man/man4/usb.4 stable/10/sys/conf/files stable/10/sys/dev/usb/usbdevs stable/10/sys/modules/usb/Makefile Directory Properties: stable/10/ (props changed) Modified: stable/10/share/man/man4/Makefile ============================================================================== --- stable/10/share/man/man4/Makefile Mon Feb 17 22:27:32 2014 (r262136) +++ stable/10/share/man/man4/Makefile Mon Feb 17 22:40:05 2014 (r262137) @@ -67,6 +67,7 @@ MAN= aac.4 \ auditpipe.4 \ aue.4 \ axe.4 \ + axge.4 \ bce.4 \ bfe.4 \ bge.4 \ Copied and modified: stable/10/share/man/man4/axge.4 (from r258331, head/share/man/man4/axge.4) ============================================================================== --- head/share/man/man4/axge.4 Tue Nov 19 00:37:53 2013 (r258331, copy source) +++ stable/10/share/man/man4/axge.4 Mon Feb 17 22:40:05 2014 (r262137) @@ -30,7 +30,7 @@ .\" .\" $FreeBSD$ .\" -.Dd November 12, 2013 +.Dd November 22, 2013 .Dt AXGE 4 .Os .Sh NAME @@ -41,6 +41,7 @@ To compile this driver into the kernel, place the following lines in your kernel configuration file: .Bd -ragged -offset indent +.Cd "device xhci" .Cd "device ehci" .Cd "device uhci" .Cd "device ohci" Modified: stable/10/share/man/man4/usb.4 ============================================================================== --- stable/10/share/man/man4/usb.4 Mon Feb 17 22:27:32 2014 (r262136) +++ stable/10/share/man/man4/usb.4 Mon Feb 17 22:40:05 2014 (r262137) @@ -24,7 +24,7 @@ .\" .\" $FreeBSD$ .\" -.Dd May 20, 2009 +.Dd November 26, 2013 .Dt USB 4 .Os .Sh NAME @@ -147,6 +147,7 @@ specifications can be found at: .Xr usbdi 4 , .Xr aue 4 , .Xr axe 4 , +.Xr axge 4 , .Xr cue 4 , .Xr ehci 4 , .Xr kue 4 , Modified: stable/10/sys/conf/files ============================================================================== --- stable/10/sys/conf/files Mon Feb 17 22:27:32 2014 (r262136) +++ stable/10/sys/conf/files Mon Feb 17 22:40:05 2014 (r262137) @@ -2342,6 +2342,7 @@ dev/usb/usb_util.c optional usb # dev/usb/net/if_aue.c optional aue dev/usb/net/if_axe.c optional axe +dev/usb/net/if_axge.c optional axge dev/usb/net/if_cdce.c optional cdce dev/usb/net/if_cue.c optional cue dev/usb/net/if_ipheth.c optional ipheth @@ -2352,8 +2353,8 @@ dev/usb/net/if_smsc.c optional smsc dev/usb/net/if_udav.c optional udav dev/usb/net/if_usie.c optional usie dev/usb/net/ruephy.c optional rue -dev/usb/net/usb_ethernet.c optional aue | axe | cdce | cue | kue | mos | \ - rue | smsc | udav | ipheth +dev/usb/net/usb_ethernet.c optional aue | axe | axge | cdce | cue | kue | \ + mos | rue | smsc | udav | ipheth dev/usb/net/uhso.c optional uhso # # USB WLAN drivers Copied: stable/10/sys/dev/usb/net/if_axge.c (from r258331, head/sys/dev/usb/net/if_axge.c) ============================================================================== --- /dev/null 00:00:00 1970 (empty, because file is newly added) +++ stable/10/sys/dev/usb/net/if_axge.c Mon Feb 17 22:40:05 2014 (r262137, copy of r258331, head/sys/dev/usb/net/if_axge.c) @@ -0,0 +1,1023 @@ +/*- + * Copyright (c) 2013 Kevin Lo + * All rights reserved. + * + * Redistribution and use in source and binary forms, with or without + * modification, are permitted provided that the following conditions + * are met: + * 1.
