Add new option required to build with VHOST_MENU=y This option enables two IOCTLs: VHOST_SET_FORK_FROM_OWNER and VHOST_GET_FORK_FROM_OWNER. These allow userspace applications to modify the vhost worker mode for vhost devices. Also expose module parameter 'fork_from_owner_default' to allow users to configure the default mode for vhost workers. By default, `VHOST_ENABLE_FORK_OWNER_CONTROL` is set to `y`, users can change the worker thread mode as needed. If this config is disabled (n),the related IOCTLs and parameters will be unavailable. If unsure, say "Y". Signed-off-by: John Audia <therealgraysky@proton.me> Link: openwrt#19618 Signed-off-by: Robert Marko <robimarko@gmail.com>

LLDP packets must be transmitted on a single port and trapped on a port of a device which understands LLDP. It must not forward it to other ports to avoid confusing neighbor information on connected devices.

This commit fixes "aff2f096235 include: make APK .list files reproducible" since it would create the .list file while `find` still runs. This causes the .list file to be part of itself. As an alternative, write the file to a temporary folder first and then move it. Fix: aff2f09 include: make APK .list files reproducible Signed-off-by: Paul Spooren <mail@aparcar.org>

The ath9k driver creates an ath9k LED by default. Instead of having a non functional LED, configure it properly and remove the extra as it's not needed. It's also a bit funny matching against phy0 and phy1 when both differ between ath9k and ath10k.

It looks like VRX518 returns phys addr of data buffer in the 'data_ptr' field of the RX descriptor and an actual data offset within the buffer in the 'byte_off' field. In order to map the phys address back to virtual we need the original phys address of the allocated buffer. In the same driver applies offset to phys address before the mapping, what leads to WARN_ON triggering in plat_mem_virt() function with subsequent kernel panic: WARNING: CPU: 0 PID: 0 at .../sw_plat.c:764 0xbf306cd0 [vrx518_tc@8af9f5d0+0x25000] ... Unable to handle kernel NULL pointer dereference at virtual address 00000000 pgd = aff5701e [00000000] *pgd=00000000 Internal error: Oops: 5 [#1] SMP ARM Noticed in ATM mode, when chip always returns byte_off = 4. In order to fix the issue, pass the phys address to plat_mem_virt() as is and apply byte_off later for proper DMA syncing and on mapped virtual address when copying RXed data into the skb.
