This scheduler allows the network administrator to configure schedules
for classes of traffic, the configuration interface is similar to what
IEEE 802.1Qbv-2015 defines.
Example configuration:
$ tc qdisc add dev enp2s0 parent root handle 100 taprio \
num_tc 3 \
map 2 2 1 0
Add this helper to read signed 64-bit integers from a string.

Hi,
This series provides a set of interfaces that can be used by
applications that require (time-based) Scheduled Transmission of

Hello,
Linux has a software implementation of the MACsec standard but so far,
to my knowledge, no hardware offloading support was developed and sent
upstream. I am working on a PHY that has an embedded MACsec engine and
would like to add support for MACsec hardware offloading in Linux in
order to

People noticed that the code match on IEEE 802.1ad (ETH_P_8021AD) ethertype,
and this implies Q-in-Q or double tagged VLANs. Thus, we better parse
the next VLAN header too. It is even marked as a TODO.
This is relevant for real world use-cases, as XDP cpumap redirect can be
used when the NIC RSS

We were returning DUPLEX_UNKNOWN in get_link_ksettings() when
the link was down. Unfortunately, this causes a problem when
"ethtool -s autoneg on" is issued for a link which is down because
the ethtool code first reads the settings and then reapplies them

The decrypted bit is propogated to cloned/copied skbs.
This will be used later by the inline crypto receive side offload
of tls.

Previously, decrypt_skb also updated the TLS context.
Now, decrypt_skb only decrypts the payload using the current context,
while decrypt_skb_update also updates the state.
Later, in the tls_device Rx flow, we will use decrypt_skb directly.
