Endpoints with zero wMaxPacketSize are not usable for transferring data. Ignore such endpoints when looking for valid in, out and status pipes, to make the drivers more robust against invalid and meaningless descriptors.

The 'mac-mode' property is similar to 'phy-mode' and 'phy-connection-type', which are enums of mode strings. The 'dwmac' driver supports almost all modes declared in the 'phy-mode' enum (except for 1 or 2). But in general, there may be a case where 'mac-mode' becomes more generic and is moved as part of phylib or netdev. In any case, the 'mac-mode' field should be made an enum, and it also makes sense to just reference the 'phy-connection-type' from 'ethernet-controller.yaml'. That will also make it more future-proof for new modes.

This pull request includes: (a) The fs/verity/ support layer and documentation. (b) fs-verity support for ext4 and f2fs. Compared to the original fs-verity patchset from last year, the UAPI to enable fs-verity on a file has been greatly simplified. Lots of other things were cleaned up too. fs-verity is planned to be used by two different projects on Android; most of the userspace code is in place already. Another userspace tool ("fsverity-utils"), and xfstests, are also available. e2fsprogs and f2fs-tools already have fs-verity support. Other people have shown interest in using fs-verity too. I've tested this on ext4 and f2fs with xfstests, both the existing tests and the new fs-verity tests.

Pull fscrypt updates from Eric Biggers: "This is a large update to fs/crypto/ which includes: - Add ioctls that add/remove encryption keys to/from a filesystem-level keyring. These fix user-reported issues where e.g. an encrypted home directory can break NetworkManager, sshd, Docker, etc. because they don't get access to the needed keyring. These ioctls also provide a way to lock encrypted directories that doesn't use the vm.drop_caches sysctl, so is faster, more reliable, and doesn't always need root. - Add a new encryption policy version ("v2") which switches to a more standard, secure, and flexible key derivation function, and starts verifying that the correct key was supplied before using it. The key derivation improvement is needed for its own sake as well as for ongoing feature work for which the current way is too inflexible. Work is in progress to update both Android and the 'fscrypt' userspace tool to use both these features. (Working patches are available and just need to be reviewed+merged.) Chrome OS will likely use them too. This has also been tested on ext4, f2fs, and ubifs with xfstests -- both the existing encryption tests, and the new tests for this.

Other than that churn, there are two "persistent" branches in here that other trees will be pulling in as well during the merge window. One branch to add support for drivers to have the driver core automatically add sysfs attribute files when a driver is bound to a device so that the driver doesn't have to manually do it (and then clean it up, as it always gets it wrong). There's another branch in here for generic lookup helpers for the driver core that lots of busses are starting to use. That's the majority of the non-driver-core changes in this patch series.
