Hi Jakub, Dave,
This series adds support for dissecting PTP L2 packet
header (EtherType 0x88F7).
For packet header dissecting, skb->protocol is needed. Add protocol
parsing operation to vlan ops, to guarantee skb->protocol is set,
as EtherType 0x88F7 occasionally follows a vlan header.
Changelog
Add parse protocol header ops for vlan device. Before this patch, vlan
tagged packet transmitted by af_packet had skb->protocol unset. Some
kernel methods (like __skb_flow_dissect()) rely on this missing information
for its packet processing.

The IPA driver depends on some SMEM functionality (qcom_smem_init(),
qcom_smem_alloc(), and qcom_smem_virt_to_phys()), but this is not
reflected in the configuration dependencies. Add a dependency on
QCOM_SMEM to avoid attempts to build the IPA driver without SMEM.
This avoids a link error for cer

In this patch two issues with TCP keepalives are fixed:
1) TCP keepalive does not timeout when there are data waiting to be
delivered and then the connection got broken. The TCP keepalive
timeout is not evaluated in that condition.
The fix is to remove the code that pre

The IPA driver uses the remoteproc SSR notifier now, rather than the
temporary IPA notification system used initially. As a result it no
longer needs a property identifying the modem subsystem DT node.
Use GIC_SPI rather than 0 in the example interrupt definition.

The IPA driver currently requires a DT property to be defined whose
value is the phandle for the modem subsystem. This was needed to
look up a remoteproc structure pointer used when registering for
notifications in the original IPA notification mechanism.
Remoteproc provides a more generic SSR no
The "modem-remoteproc" property is no longer required for the IPA
driver, so get rid of it.

Unlike the original (temporary) IPA notification mechanism, the
generic remoteproc SSR notification code does not require the IPA
driver to maintain a pointer to the modem subsystem remoteproc
structure.
The IPA driver was converted to use the newer SSR notifiers, but the

Existing TUN module is able to use provided "steering eBPF" to
calculate per-packet hash and derive the destination queue to
place the packet to. The eBPF uses mapped configuration data
containing a key for hash calculation and indirection table
with array of queues' indices.

The module never creates the bpf program with bpf_prog_create
so it shouldn't free it with bpf_prog_destroy.
The program is obtained by bpf_prog_get and should be freed
by bpf_prog_put. For BPF_PROG_TYPE_SOCKET_FILTER both
methods do the same but for other program types they don't.
