The method ndo_start_xmit() is defined as returning an 'netdev_tx_t',
which is a typedef for an enum type, so make sure the implementation in
this driver has returns 'netdev_tx_t' value, and change the function
return type to netdev_tx_t.

3. Add two response lists for lio_process_ordered_list to process the

the pool after their requestors have finished processing the responses.
OCTEON_ZOMBIE_SC_LIST response list keeps all sc's which have got
LIO_SC_MAX_TMO_MS timeout.
When an sc gets a hard timeout, lio_process_order_list() will recheck
its status 1 ms later. If the status has not updated by the firmware at
that time, the sc will be removed from OCTEON_DONE_SC_LIST response list
to OCTEON_ZOMBIE_SC_LIST response list. The sc's in the
OCTEON_ZOMBIE_SC_LIST response list will be freed when the driver is

octeon_mgmt driver doesn't drop RX frames that are 1-4 bytes bigger than
MTU set for the corresponding interface. The problem is in the
AGL_GMX_RX0/1_FRM_MAX register setting, which should not account for VLAN
tagging.
According to Octeon HW manual:
"For tagged frames, MAX increases by four bytes for each VLAN found up to a
maximum of two VLANs, or MAX + 8 bytes."
OCTEON_FRAME_HEADER_LEN "define" is fine for ring buffer management, but
should not be used for AGL_GMX_RX0/1_FRM_MAX.
The problem could be easily reproduced using "ping" command. If affected
system has default MTU 1500, other host (having MTU >= 1504) can
successfully "ping" the affected system with payload size 1473-1476,
resulting in IP packets of size 1501-1504 accepted by the mgmt driver.
Fixed system still accepts IP packets of 1500 bytes even with VLAN tagging,
because the limits are lifted in HW as expected, for every VLAN tag.

pull-request: bpf-next 2018-07-15
The following pull-request contains BPF updates for your *net-next* tree.
The main changes are:
1) Various different arm32 JIT improvements in order to optimize code emission
and make the JIT code itself more robust, from Russell.
2) Support simultaneous driver and offloaded XDP in order to allow for advanced
use-cases where some work is offloaded to the NIC and some to the host. Also
add ability for bpftool to load programs and maps beyond just the cgroup case,
from Jakub.
3) Add BPF JIT support in nfp for multiplication as well as division. For the
latter in particular, it uses the reciprocal algorithm to emulate it, from Jiong.
4) Add BTF pretty print functionality to bpftool in plain and JSON output
format, from Okash.
5) Add build and installation to the BPF helper man page into bpftool, from Quentin.
6) Add a TCP BPF callback for listening sockets which is triggered right after
the socket transitions to TCP_LISTEN state, from Andrey.
7) Add a new cgroup tree command to bpftool which iterates over the whole cgroup
tree and prints all attached programs, from Roman.
8) Improve xdp_redirect_cpu sample to support parsing of double VLAN tagged
packets, from Jesper.

prog_attached of struct netdev_bpf should have been superseded
by simply setting prog_id long time ago, but we kept it around
to allow offloading drivers to communicate attachment mode (drv
vs hw). Subsequently drivers were also allowed to report back
attachment flags (prog_flags), and since nowadays only programs
attached will XDP_FLAGS_HW_MODE can get offloaded, we can tell
the attachment mode from the flags driver reports. Remove
prog_attached member.

Currently ThunderX NICVF driver has only one ordered workqueue to process
