MFC r328342:

2018-04-16T17:15:26Z

Add SPDX identifiers to linux_ptrace.c and cfumass.c.

Revert r330897:

2018-03-29T02:50:57Z

This was intended to be a non-functional change. It wasn't. The commit message was thus wrong. In addition it broke arm, and merged crypto related code. Revert with prejudice. This revert skips files touched in r316370 since that commit was since MFCed. This revert also skips files that require $FreeBSD$ property changes. Thank you to those who helped me get out of this mess including but not limited to gonzo, kevans, rgrimes. Requested by: gjb (re)

Partial merge of the SPDX changes

2018-03-14T03:19:51Z

These changes are incomplete but are making it difficult to determine what other changes can/should be merged. No objections from: pfg

MFC r314290: Implement use of multiple transfers per I/O.

2017-04-23T09:01:40Z

This change removes limitation of single S/G list entry and limitation on maximal I/O size, using multiple data transfers per I/O if needed. Also it removes code duplication between send and receive paths, which are now completely equal.

MFC r314256: Use ctl_queue_sense() to implement sense data reporting.

2017-04-23T09:01:01Z

USB MS BBB transport does not support autosense, so we have to queue any sense data back to CTL for later fetching via REQUEST SENSE.

MFC r314254: Update kern_data_resid according to r312291.

2017-04-23T09:00:26Z

This now mandatory for correct operation.

MFC r313959:

2017-04-09T19:30:49Z

Add USB Mass Storage CTL frontend. This makes it possible for USB OTG-capable hardware to implement device side of USB Mass Storage, ie pretend it's a flash drive. It's configured in the same way as other CTL frontends, using ctladm(8) or ctld(8). Differently from usfs(4), all the configuration can be done without rebuilding the kernel. Testing and review is welcome. Right now I'm still moving, and I don't have access to my test environment, so I'm somewhat reluctant to making larger changes to this code; on the other hand I don't want to let it sit on Phab until my testing setup is back, because I want to get it into 11.1-RELEASE.

Create a USB_PNP_INFO and use it to export the existing PNP

2015-12-11T05:28:00Z

tables. Some drivers needed some slight re-arrangement of declarations to accommodate this. Change the USB pnp tables slightly to allow better compatibility with the system by moving linux driver info from start of each entry to the end. All other PNP tables in the system have the per-device flags and such at the end of the elements rather that at the beginning. Differential Review: https://reviews.freebsd.org/D3458

Use define instead of constant.
