Florian Fainelli a5d78ce793 net: systemport: Add software counters to track reallocations
When inserting the TSB, keep track of how many times we had to do it and
if there was a failure in doing so, this helps profile the driver for
possibly incorrect headroom settings.

Florian Fainelli 10b476c57b net: systemport: Refactor bcm_sysport_set_features()
In preparation for unconditionally enabling TX and RX checksum offloads,
refactor bcm_sysport_set_features() a bit such that
__netdev_update_features() during register_netdev() can make sure that
features are correctly programmed during network device registration.

Since we can now be called during register_netdev() with clocks gated,
we need to temporarily turn them on/off in order to have a successful
register programming.

We also move the CRC forward setting read into
bcm_sysport_set_features() since priv->crc_fwd matters while turning on
RX checksum offload, that way we are guaranteed they are in sync in case
we ever add support for NETIF_F_RXFCS at some point in the future.

Eric Dumazet 58e0e22bff bnxt: remove ndo_poll_controller
As diagnosed by Song Liu, ndo_poll_controller() can
be very dangerous on loaded hosts, since the cpu
calling ndo_poll_controller() might steal all NAPI
contexts (for all RX/TX queues of the NIC). This capture
can last for unlimited amount of time, since one
cpu is generally not able to drain all the queues under load.

bnxt uses NAPI for TX completions, so we better let core
networking stack call the napi->poll() to avoid the capture.

Michael Chan 00fe9c326d bnxt_en: Do not adjust max_cp_rings by the ones used by RDMA.
Currently, the driver adjusts the bp->hw_resc.max_cp_rings by the number
of MSIX vectors used by RDMA.  There is one code path in open that needs
to check the true max_cp_rings including any used by RDMA.  This code
is now checking for the reduced max_cp_rings which will fail when the
number of cp rings is very small.

To fix this in a clean way, we don't adjust max_cp_rings anymore.
Instead, we add a helper bnxt_get_max_func_cp_rings_for_en() to get the
reduced max_cp_rings when appropriate.

Florian Fainelli bb9051a2b2 net: systemport: Add support for WAKE_FILTER
The SYSTEMPORT MAC allows up to 8 filters to be programmed to wake-up
from LAN. Verify that we have up to 8 filters and program them to the
appropriate RXCHK entries to be matched (along with their masks).

We need to update the entry and exit to Wake-on-LAN mode to keep the
RXCHK engine running to match during suspend, but this is otherwise
fairly similar to Magic Packet detection.

Michael Chan aabfc016e9 bnxt_en: Do not use the CNP CoS queue for networking traffic.
The CNP CoS queue is reserved for internal RDMA Congestion Notification
Packets (CNP) and should not be used for a TC.  Modify the CoS queue
discovery code to skip over the CNP CoS queue and to reduce
bp->max_tc accordingly.  However, if RDMA is disabled in NVRAM, the
the CNP CoS queue can be used for a TC.

Michael Chan afdc8a8484 bnxt_en: Add DCBNL DSCP application protocol support.
Expand the .ieee_setapp() and ieee_delapp() DCBNL methods to support
DSCP.  This allows DSCP values to user priority mappings instead
of using VLAN priorities.  Each DSCP mapping is added or deleted one
entry at a time using the firmware API.  The firmware call can only be
made from a PF.

Michael Chan 50f011b63d bnxt_en: Update RSS setup and GRO-HW logic according to the latest spec.
Set the default hash mode flag in HWRM_VNIC_RSS_CFG to signal to the
firmware that the driver is compliant with the latest spec.  With
that, the firmware can return expanded RSS profile IDs that the driver
checks to setup the proper gso_type for GRO-HW packets.  But instead
of checking for the new profile IDs, we check the IP_TYPE flag
in TPA_START which is more straight forward than checking a list of
profile IDs.
