631185273b enic: devcmd for adding IP 5 tuple hardware filters
This patch adds interface to add and delete IP 5 tuple filter. This interface
is used by Accelerated RFS code to steer a flow to corresponding receive
queue.

As of now adaptor supports only ipv4 + tcp/udp packet steering.

10cc88446c enic: fix return value in _vnic_dev_cmd
Hardware (in readq(&devcmd->args[0])) returns positive number in case of error.
But _vnic_dev_cmd should return a negative value in case of error.

f009618ac5 enic: Update driver to use __dev_uc/mc_sync/unsync calls
This change updates the enic driver to make use of __dev_uc_sync and
__dev_mc_sync calls.  Previously the driver was doing its own list
management by storing the mc_addr and uc_addr list in a 32 address array.
With this change the sync data is stored in the netdev_addr_list structures
and instead we just track how many addresses we have written to the device.
When we encounter 32 we stop and print a message as occurred previously with
the old approach.

Other than the core change the only other bit needed was to propagate the
constant attribute with the MAC address as there were several spots where
is twas only passed as a u8 * instead of a const u8 *.

This patch is meant to maintain the original functionality without the use
of the mc_addr and uc_addr arrays.

07783f39e1 enic: be less verbose about non-critical firmware errors
If a feature is not supported by firmware no need to print an error message.
This surpresses the following harmless message on boot up and ethtool query.
enic: Error 1 devcmd 36
