zhong jiang 880e1b2111 net: liquidio: list usage cleanup
Trival cleanup, list_move_tail will implement the same function that
list_del() + list_add_tail() will do. hence just replace them.

YueHaibing ac1172dea1 net: cavium: fix return type of ndo_start_xmit function
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.

There will be no packets coming in after hitting this level. So NAPI will

Felix Manlunas c9aec05228 liquidio: improve soft command handling
1. Set LIO_SC_MAX_TMO_MS as the maximum timeout value for a soft command
   (sc).  All sc's use this value as a hard timeout value. Add expiry_time
   in struct octeon_soft_command to keep the hard timeout value. The field
   wait_time and timeout in struct octeon_soft_command will be obsoleted in
   the last patch of this patch series.
2. Add processing a synchronous sc in sc response thread
   lio_process_ordered_list. The memory allocated for a synchronous sc will
   be freed by lio_process_ordered_list() to the sc pool.
3. Add two response lists for lio_process_ordered_list to process the
   storage allocated for sc's:
   OCTEON_DONE_SC_LIST response list keeps all sc's which will be freed to
   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
   unloaded.

All control commands (soft commands) goes through only Queue 0
(control and data queue). So only queue-0 needs post_lock,
other queues are only data queues and does not need post_lock

Added a flag to indicate the queue can be used for soft commands.

If this flag is set, post_lock must be acquired before posting
a command to the queue.
If this flag is clear, post_lock is invalid for the queue.

Rick Farrington ac13d6d8ea liquidio: fix hang when re-binding VF host drv after running DPDK VF driver
When configuring SLI_PKTn_OUTPUT_CONTROL, VF driver was assuming that IPTR
mode was disabled by reset, which was not true.  Since DPDK driver had
set IPTR mode previously, the VF driver (which uses buf-ptr-only mode) was
not properly handling DROQ packets (i.e. it saw zero-length packets).

This represented an invalid hardware configuration which the driver could
not handle.

Pre-1.7.2 NIC firmware does not support (and does not respond to) the "get
speed" command which is sent by the 1.7.2 driver (for CN23XX-225 cards
only) during modprobe.  Due to a bug in older firmware (with respect to
unknown commands), this unsupported command causes a cascade of errors that
ends in a kernel panic.

Fix it by making the sending of the "get speed" command conditional on the
firmware version.

Kees Cook fd7becedb1 treewide: Use array_size() in vzalloc_node()
The vzalloc_node() function has no 2-factor argument form, so
multiplication factors need to be wrapped in array_size(). This patch
replaces cases of:

        vzalloc_node(a * b, node)

with:
        vzalloc_node(array_size(a, b), node)

as well as handling cases of:

        vzalloc_node(a * b * c, node)

with:

        vzalloc_node(array3_size(a, b, c), node)

This does, however, attempt to ignore constant size factors like:

        vzalloc_node(4 * 1024, node)

though any constants defined via macros get caught up in the conversion.

Any factors with a sizeof() of "unsigned char", "char", and "u8" were
dropped, since they're redundant.

The Coccinelle script used for this was:

Kees Cook fad953ce0b treewide: Use array_size() in vzalloc()
The vzalloc() function has no 2-factor argument form, so multiplication
factors need to be wrapped in array_size(). This patch replaces cases of:

        vzalloc(a * b)

with:
        vzalloc(array_size(a, b))

as well as handling cases of:

        vzalloc(a * b * c)

with:

        vzalloc(array3_size(a, b, c))

This does, however, attempt to ignore constant size factors like:

        vzalloc(4 * 1024)

though any constants defined via macros get caught up in the conversion.

Any factors with a sizeof() of "unsigned char", "char", and "u8" were
dropped, since they're redundant.

The Coccinelle script used for this was:

// Fix redundant parens around sizeof().

NIC firmware does not support disabling rx vlan offload, but the VF driver
incorrectly indicates that it is supported.  The PF driver already does the
correct indication by clearing the NETIF_F_HW_VLAN_CTAG_RX bit in its
