When offloading classifiers such as u32 or flower to hardware, and the
qdisc is clsact (TC_H_CLSACT), then we need to differentiate its classes,
since not all of them handle ingress, therefore we must leave those in
software path. Add a .tcf_cl_offload() callback, so we can generically
handle them, tested on ixgbe.

RDS: TCP: socket locking RDS packet assembly fixes
This three part patchset fixes bugs in synchronization between
rds_tcp_accept_one() and the rds-tcp send/recv path.
Patch 1 ensures that the lock_sock() is taken appropriately
and the RDS datagram reassembly state is reset to synchronize
with the receive path.
Patch 2 ensures that partially sent RDS datagrams will get
retransmitted after rds_tcp_accept_one() switches sockets.
Patch 3 fixes a race window which would prematurely re-enable
rds_send_xmit() before the rds_tcp_connection setup has been
completed in rds_tcp_accept_one().
====================
Signed-off-by: David S. Miller <davem@davemloft.net>
The send path needs to be quiesced before resetting callbacks from
rds_tcp_accept_one(), and commit eb19284026 ("RDS:TCP: Synchronize
rds_tcp_accept_one with rds_send_xmit when resetting t_sock") achieves
this using the c_state and RDS_IN_XMIT bit following the pattern
used by rds_conn_shutdown(). However this leaves the possibility
of a race window as shown in the sequence below
take t_conn_lock in rds_tcp_conn_connect
send outgoing syn to peer
drop t_conn_lock in rds_tcp_conn_connect
incoming from peer triggers rds_tcp_accept_one, conn is
marked CONNECTING
wait for RDS_IN_XMIT to quiesce any rds_send_xmit threads
call rds_tcp_reset_callbacks
[.. race-window where incoming syn-ack can cause the conn
to be marked UP from rds_tcp_state_change ..]
lock_sock called from rds_tcp_reset_callbacks, and we set
t_sock to null
As soon as the conn is marked UP in the race-window above, rds_send_xmit()
threads will proceed to rds_tcp_xmit and may encounter a null-pointer
deref on the t_sock.
Given that rds_tcp_state_change() is invoked in softirq context, whereas
rds_tcp_reset_callbacks() is in workq context, and testing for RDS_IN_XMIT
after lock_sock could result in a deadlock with tcp_sendmsg, this
commit fixes the race by using a new c_state, RDS_TCP_RESETTING, which
will prevent a transition to RDS_CONN_UP from rds_tcp_state_change().

When rds_tcp_accept_one() has to replace the existing tcp socket
with a newer tcp socket (duelling-syn resolution), it must lock_sock()
to suppress the rds_tcp_data_recv() path while callbacks are being
changed. Also, existing RDS datagram reassembly state must be reset,
so that the next datagram on the new socket does not have corrupted
state. Similarly when resetting the newly accepted socket, appropriate
locks and synchronization is needed.
This commit ensures correct synchronization by invoking
kernel_sock_shutdown to reset a newly accepted sock, and by taking
appropriate lock_sock()s (for old and new sockets) when resetting
existing callbacks.

Since implementing VLAN filtering in commit 05cc5a39dd
("bnx2x: add vlan filtering offload") bnx2x refuses to add a VLAN while
the interface is down:
# ip link add link enp3s0f0 enp3s0f0_10 type vlan id 10
RTNETLINK answers: Bad address
and in dmesg (with bnx2x.debug=0x20):
bnx2x: [bnx2x_vlan_rx_add_vid:12941(enp3s0f0)]Ignoring VLAN
configuration the interface is down
Other drivers have no problem with this.
Fix this peculiar behavior in the following way:
- Accept requests to add/kill VID regardless of the device state.
Maintain the requested list of VIDs in the bp->vlan_reg list.
- If the device is up, try to configure the VID list into the hardware.
If we run out of VLAN credits or encounter a failure configuring an
entry, fall back to accepting all VLANs.
If we successfully configure all entries from the list, turn the
fallback off.
- Use the same code for reconfiguring VLANs during NIC load.

If an external Gigabit PHY is connected to either of the MACs we need to

We tell the PHY which MII delay mode to use via the devictree.
The ethernet driver needs to be adapted to handle all 3 rgmii-*id modes
in the same way as normal rgmii when setting up the MAC.

atomic context triggering 'scheduling while atomic'.
The stmmac_priv lock usage is not fully documented, but it seems
to protect the access to the MAC registers / DMA structures rather
than the MDIO bus or the PHY (which have separate locking),
so we can push the spin_lock after the stmmac_mdio_reset call.

While this warning is only about the specific case of CONFIG_QED_SRIOV
being disabled but the function getting called for a VF (which should
never happen), another possibility is that qed_mcp_get_*() fails without

This rearranges the code so we bail out in either of the two cases

The qed_link_output structure remains untouched in this case, but
all callers first call memset() on it, so at least we are not leaking
stack data then.
As discussed, we also use a compile-time check to ensure we never
use any of the VF code if CONFIG_QED_SRIOV is disabled, and the
