* USB: rndis: section mismatch fixHenrik Kretzschmar2010-09-031-1/+1
| | | | | | | | | | | | | | | This patch removes the following section mismatch warning, by moving the function rndis_init() from .init.text to .text. WARNING: vmlinux.o(.text+0x1aeca5a): Section mismatch in reference from the function rndis_bind_config() to the function .init.text:rndis_init() The function rndis_bind_config() references the function __init rndis_init(). This is often because rndis_bind_config lacks a __init annotation or the annotation of rndis_init is wrong.

* USB: gadget: Add EEM gadget driverBrian Niebuhr2009-09-231-1/+2
| | | | | | | | | | | | | | | | | | This patch adds a CDC EEM ethernet gadget driver. CDC EEM is a newer USB ethernet specification that uses a simpler interface than the older CDC ECM. This makes CDC EEM usable by a wider set of USB hardware. By default the ethernet gadget will still use CDC ECM/Subset, but kernel configuration and/or a module parameter will allow alternative use of the CDC EEM protocol. Changes since last version: - Brought in missing RNDIS changes that caused compile error - Modified 'sentinel CRC' checking to match EEM host driver Signed-off-by: Brian Niebuhr <bniebuhr@efjohnson.com> Cc: David Brownell <dbrownell@users.sourceforge.net> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
* usb gadget: RNDIS cleanupsDavid Brownell2008-07-211-4/+3
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Some cleanup to the RNDIS code: - Minor bugfix: rndis_unit() is supposed to put the link into the RNDIS_UNINITIALIZED state, which does not mean "unused". There's a separate method to stop using the link. (Bug doesn't affect anything right now because of how the code is used.) - Reduce coupling between RNDIS code and its user(s), in preparation for updates in that code: * Decouple RNDIS_RESPONSE_AVAILABLE notifications from net_device by passing just a void* handle. (Also, remove the unused return value of the notification callback.) * When it needs a copy of net_device stats, just ask for it - Remove unused/untested code backing various never-used OIDs: * RNDIS_PM, RNDIS_WAKEUP ... "should" get implemented, but the relevant docs were unclear, ambguous, and incomplete. Someone with access to the Hidden Gospels (maybe in the EU?) might be able to figure out what this should do. * RNDIS_OPTIONAL_STATS ... as the name suggests, optional. Never implemented in part because not all the semantics were clear. * OID_GEN_RNDIS_CONFIG_PARAMETER, which has been #if 0 forever. - A few small whitespace fixes Plus switch the VERBOSE symbol over to the newer VERBOSE_DEBUG style. There should be no functional changes because of this patch; it's a net source code shrink (because of the dead/unused code removal) and a small object code shrink (a couple hundred bytes on ARMv5).

* [PATCH] USB: gadget section fixupsDavid Brownell2006-07-121-1/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | Recent section changes broke gadget builds on some platforms. This patch is the best fix that's available until better section markings exist: - There's a lot of cleanup code that gets used in both init and exit paths; stop marking it as "__exit". (Best fix for this would be an "__init_or_exit" section marking, putting the cleanup in __init when __exit sections get discarded else in __exit.) - Stop marking the use-once probe routines as "__init" since references to those routines are not allowed from driver structures. They're now marked "__devinit", which in practice is a net lose. (Best fix for this is likely to separate such use-once probe routines from the driver structure ... but in general, all busses that aren't hotpluggable will be forced to waste memory for all probe-only code.) In general these broken section rules waste an average of two to four kBytes per driver of code bloat ... because none of the relevant code can ever be reused after module initialization.

* [PATCH] USB: whitespace removal from usb/gadget/etherDavid Brownell2006-06-211-13/+13

* [PATCH] USB: rndis updates (mostly cleanup)David Brownell2005-06-271-87/+8
| | | | | | | | | | | | | | | | | | | | | Some bugfixes and lots of cleanup (net code shrink): - On reset, force the RNDIS state machine its initial state - Hook up the RNDIS (outgoing) filters to the CDC mechanism - Lots of cleanup: * Eliminate duplicate copy of OID table; * Unify handlying of the OID "query" response data pointer; * Reduce code duplication for calculating query response lengths; * Remove some checks for "can't happen" errors; * Get rid of debugging #ifdefs by making the debug flag an integer level Most of the patch, by volume, relates to those query response cleanups. It incidentally shaves off a few hundred bytes of object code. Signed-off-by: David Brownell <dbrownell@users.sourceforge.net> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
* [PATCH] usb gadget: ethernet/rndis updatesDavid Brownell2005-04-181-1/+2
| | | | | | | | | | | | | | | | | | | | | | | | | | | Updates to the Ethernet/RNDIS gadget driver (mostly for RNDIS): - Fix brown-paper bag goof with RNDIS packet TX ... the wrong length field got set, so Windows would ignore data packets it received. - More consistent handling of CDC output filters (but not yet hooking things up so RNDIS uses the mechanism). - Zerocopy RX for RNDIS packets too (saving CPU cycles). - Use the pre-allocated interrupt/status request and buffer, rather than allocating and freeing one of each every few seconds (which could fail). - Some more "sparse" tweaks, making both dual-speed and single-speed configurations happier. - RNDIS speeds are reported in units of 100bps, not bps. Plus two minor cleanups (whitespace, messaging). Signed-off-by: David Brownell <dbrownell@users.sourceforge.net> Signed-off-by: Greg Kroah-Hartman <gregkh@suse.de>
* Linux-2.6.12-rc2v2.6.12-rc2Linus Torvalds2005-04-161-0/+348
Initial git repository build. I'm not bothering with the full history, even though we have it. We can create a separate "historical" git archive of that later if we want to, and in the meantime it's about 3.2GB when imported into git - space that would just make the early git days unnecessarily complicated, when we don't have a lot of good infrastructure for it. Let it rip!
