100GbE Intel Wired LAN Driver Updates 2016-04-20
This series contains updates to fm10k only.
Jacob provides majority of the changes in this series, starting with the
addition of helper functions to reduce code duplication and the amount
of code indentation. Fixed the use or should we say abuse of the ethtool
stats API, which could result in corrupt memory or misleading statistic
output. Added the appropriate rtnl_lock() and rtnl_unlock() to avoid
RCU warnings during AER events. Come to find out, the PTP/1588 support
is not working with the current version of switch management software
and possibly never worked, so just remove support for PTP/1588 for now.
Fixed how error responses from the switch manager after a LPORT_MAP
request are handled, originally which were silently being ignored.
Fixed up code documentation to hopefully ease the code and comment
comprehension. Fixed a possible NULL pointer dereference after a
kcalloc(), where when writing a new default redirection table, and we
needed to populate a new RSS table using ethtool_rxfh_indir_default().
We populate this table into a region of memory allocated using kcalloc()
but never check it for NULL.
Alex adds support for bulk transmit cleanup for fm10k, like he did for
all of our other drivers.
Ngai-Mint fixes a number of issues with the unicast and multicast address
syncs. Where an issue would occur when the netdev is pre-configured to

fm10k_tlv_parse_attr is supposed to return FM10K_NOT_IMPLEMENTED for any
TLV who's attribute id lies outside the range of results. It does not do
this today. In addition, the documentation does not indicate that other
attributes which are not implemented for a given TLV will be silently
ignored. Fix this. Clean up the logic so that we don't rely on the fact
that FM10K_NOT_IMPLEMENTED is greater than zero, as this can easily
cause confusion.
A future extension could look into some way of reporting unknown TLVs
in order to make issues more easily discoverable. We can't just return
FM10K_NOT_IMPLEMENTED here because we don't want to drop the entire
message if it has an unknown TLV.

fm10k_io_error_detected() does not need to call pci_disable_device(). In
the cases where the reset needs to occur, the stack flow will result in
calling fm10k_remove() which already disables the PCI device. If we
leave the pci_disable_device(), we result in a warning about disabling
an already disabled device.
Many PCI drivers do call pci_disable_device() in their .error_detected()
routines, but it does not appear to be required. In addition, these
drivers have a check "is_pci_enabled()" call in their remove routines,
which is how they chose to handle the duplicate device disable.
This seems incorrect, since the PCI device structure is reference
counted. It is very possible that the reference count for the PCI device
could be greater than 1. In this case, you would remove the PCI device
within the error_detected routine, reducing count to 1, then remove it
again in the remove function, reducing it to zero. This would result in
yet another disable somewhere else failing. Thus, we shouldn't be using
is_pci_enabled() to check for this issue. Instead, just remove the
extraneous pci_device_disable() found within the error_detected routine.

Currently, any error responses from the switch manager after an
LPORT_MAP request are silently ignored. At most the mailbox message will
be reported as an error. This can result in unexpected behavior when the
switch manager has configured a port with zero bandwidth. Add support
for reading the fm10k_swapi_error structure from LPORT_MAP responses.
If the message contains the necessary TLV and has a non-zero error code,
report link down, clear the dglort_map, and delay the next
get_host_state call by a reasonable delay. Also log an error message
indicating that the LPORT_MAP request failed.
The delay ensures preventing an interrupt storm on the switch manager,
and reduces the number of mailbox messages we send in this scenario
drastically.

Multicast mode checking is no longer a requirement to perform unicast
and multicast address syncs. Specifically, a device operating in
promiscuous and/or all multicast mode is not excluded. The issue occurs
when the netdev is pre-configured to either multicast mode and is
enabled for the first time. The multicast-group table in the Switch
Manager will be missing obvious multicast entries associated to this
netdev.
Changes were also made to disallow unicast and multicast syncs with
VLAN 0. The Switch Manager considers VLAN 0 to be an invalid entry.
Requests with VLAN 0 by the netdev are only generated when the driver is
freshly installed and the default VID is not set.

During an AER action response, we were calling fm10k_close without
holding the rtnl_lock() which could lead to possible RCU warnings being
produced due to 64bit stat updates among other causes. Similarly, we
need rtnl_lock() around fm10k_open during fm10k_io_resume. Follow the
same pattern elsewhere in the driver and protect the entire open/close
sequence.
