When a new action is installed, firstuse field of 'tcf_t' is explicitly set
to 0. Value of zero means "new action, not yet used"; as a packet hits the
action, 'firstuse' is stamped with the current jiffies value.
tcf_tm_dump() should return 0 for firstuse if action has not yet been hit.

Declaring and instantiating BPF ring buffer doesn't require any changes to
libbpf, as it's just another type of maps. So using existing BTF-defined maps

Hi Finn,

Good catch. I'm not sure about the fix though. That variable ('addr')
should be a ethernet hardware address; I'm surprised we're accessing
past the 6th byte. The culprit seems to be this, where 'ea' is the
address buffer

PHY loopback is already supported by genphy driver. This patch
adds the set_loopback interface to RTL8211F PHY driver, so the PHY
selftest can run properly on it.

Hi all,
Today's linux-next merge of the jc_docs tree got a conflict in:

This is just a question of __user tags missing in a couple of places,

I am trying to understand the resistance here. There are ingress/egress
hooks for most of the layers - tc, netfilter, and even within bpf APIs.
Clearly there is a need for this kind of symmetry across the APIs, so
why the resistance or hesitation for XDP?

According to the 8021q standard, the VLAN id range is 1 to 4095.
But in the register_vlan_device function, the range is 1 to 4094,
because ">= VLAN_VID_MASK" is used to determine whether the id
is illegal. This will prevent the creation of the vlan4095 interface:

Hi Dave,
this series moves the compat_ioctl handlers into the protocol handlers,
avoiding the need to override the address space limited as in the current
handler.
Changes since v3:
- moar variable reordering
Changes since v1:
- reorder a bunch of variable declarations
Add a helper than can be shared with the upcoming compat ioctl handler.
