Pull bootconfig fixes from Steven Rostedt: "A couple of fixes for bootconfig.

This is a follow-up patch to fix an issue left in commit:
98b0bf02738004829d7e26d6cb47b2e469aaba86
selftests: kvm: Use a shorter encoding to clear RAX
With the change in the commit, we also need to modify "xor" instruction
length from 3 to 2 in array ss_size accordingly to pass below check:
for (i = 0; i < (sizeof(ss_size) / sizeof(ss_size[0])); i++) {
target_rip += ss_size[i];

Pull networking fixes from Jakub Kicinski: - fix failure to add bond interfaces to a bridge, the offload-handling code was too defensive there and recent refactoring unearthed that. Users complained (Ido) - fix unnecessarily reflecting ECN bits within TOS values / QoS marking in TCP ACK and reset packets (Wei) - fix a deadlock with bpf iterator. Hopefully we're in the clear on this front now...

It would seem none of the kernel continuous integration does this:
$ cd tools/io_uring
$ make
Otherwise it may have noticed:
cc -Wall -Wextra -g -D_GNU_SOURCE -c -o io_uring-bench.o
io_uring-bench.c
io_uring-bench.c:133:12: error: static declaration of ‘gettid’
follows non-static declaration
133 | static int gettid(void)
| ^~~~~~
In file included from /usr/include/unistd.h:1170,
from io_uring-bench.c:27:
/usr/include/x86_64-linux-gnu/bits/unistd_ext.h:34:16: note:
previous declaration of ‘gettid’ was here
34 | extern __pid_t gettid (void) __THROW;
| ^~~~~~
make: *** [<builtin>: io_uring-bench.o] Error 1
The problem on Ubuntu 20.04 (with lk 5.9.0-rc5) is that unistd.h
already defines gettid(). So prefix the local definition with
"lk_".
