Commit f39908d3b1c45 ('net: dsa: mv88e6xxx: Set the CMODE for mv88e6390

This patch removes the definition of PGV_FROM_VMALLOC from af_packet.c.
The PGV_FROM_VMALLOC definition was already removed by

I am implementing userspace access to socket information for AF_VSOCK.
A few hours into writing and testing a /proc/net/vsock seq_file I
noticed that ss(8) prefers NETLINK_SOCK_DIAG over procfs.
Before potentially wasting time implementing a legacy interface that
won't be accepted, I thought it mi

Note sig_ind() uses out of boundary bit to (looks like) protect against

This also adds support for non-QSFP modules attached to QSFP.

My apologies Leon - I did not infer that the subject line should have been

Currently, the switchdev objects are embedded inside the DSA notifier
info. This patch removes this dependency. This is done as a preparation
stage before adding support for learning FDB through the switchdev

Currently the bridge port flags, vlans, FDBs and MDBs can be offloaded
through the bridge code, making the switchdev's SELF bridge bypass
implementation to be redundant. This implies several changes:
- No need for dump infra in switchdev, DSA's special case is handled
privately.
- Remove obj_dump

Due to this it is removed from switchdev and moved inside DSA.

The patchset moves the DSA driver into learning static FDB entries via
the switchdev notification chain rather then by using bridge bypass SELF
flag.
The DSA drivers cannot sync the software bridge with hardware learned
entries and use the switchdev's implementation of bypass FDB dumping.

In existing implementation we reset dwmac only after second module
