The netlink conflict dealt with moving to netlink_capable() and

BPF testsuite and cleanup

This patchset adds BPF testsuite and improves readability of classic
to internal BPF converter.

The testsuite helped to find 'negative offset bug' in x64 JIT that was
fixed by commit fdfaf64e ("x86: bpf_jit: support negative offsets")

It can be very useful for classic and internal JIT compiler developers.
Also it serves as performance benchmark.

x86_64/i386 pass all tests with and without JIT. arm32 JIT is failing
negative offset tests which are unsupported.

Internal BPF tests are much larger than classic tests to cover different
combinations of registers. Negative tests check correctness of classic
BPF verifier which must reject them.

This revert commit efb842c4("sctp: optimize the sctp_sysctl_net_register"),
Since it doesn't kmemdup a sysctl_table for init_net, so the
init_net->sctp.sysctl_header->ctl_table_arg points to sctp_net_table
which is a static array pointer. So when doing sctp_sysctl_net_unregister,
it will free sctp_net_table, then we will get a NULL pointer dereference

This reverts commit f8d56d8f ("net:
 eth: cpsw: Correctly attach to GPIO bitbang MDIO driver").

Fix potential null-pointer dereference at probe if the mdio-gpio device
has not been successfully probed yet.

The offending commit is plain wrong for a number of reasons. First of
all it accesses internal driver data of an unrelated device. Neither
does it check that the data is non-null (which it is in case the device
has not been probed yet).

Furthermore, the decision on whether to treat any driver data according
to the mdio-gpio driver's internals is made based on the node name. But
the name is not compared against "mdio" which is the normal name for the
node, but rather against "gpio" which the node does not have to be named
(and shouldn't be according to the binding documentation). [ If this
hack is to be kept out-of-tree it should at least be matching against
the compatible property. ]

This driver maps 802.1q VLANs to MBIM sessions. The mapping is based on
a bogus assumption that all tagged frames will use the acceleration API
because we enable NETIF_F_HW_VLAN_CTAG_TX. This fails for e.g. frames
tagged in userspace using packet sockets. Such frames will erroneously
be considered as untagged and silently dropped based on not being IP.

Fix by falling back to looking into the ethernet header for a tag if no
accelerated tag was found.
