net: thunderx: Don't set RX_PACKET_DIS while initializing

BugLink: http://bugs.launchpad.net/bugs/1630038

Setting BGXX_SPUX_MISC_CONTROL::RX_PACKET_DIS is not needed as
packet reception is anyway disabled by BGXX_CMRX_CONFIG::DATA_PKT_RX_EN.
Also setting RX_PACKET_DIS causes a bogus remote fault condition
which delays link detection.

net: thunderx: Fix for issues with multiple CQEs posted for a TSO packet

BugLink: http://bugs.launchpad.net/bugs/1624569

On ThunderX 88xx pass 2.x chips when TSO is offloaded to HW,
HW posts a CQE for every TSO segment transmitted. Current code
does handles this, but is prone to issues when segment sizes are
small resulting in SW processing too many CQEs and also at times
frees a SKB which is not yet transmitted.

This patch handles the errata in a different way and eliminates issues
with earlier approach, TSO packet is submitted to HW with post_cqe=0,
so that no CQE is posted upon completion of transmission of TSO packet
but a additional HDR + IMMEDIATE descriptors are added to SQ due to
which a CQE is posted and will have required info to be used while
cleanup in napi. This way only one CQE is posted for a TSO packet.

UBUNTU: SAUCE: net: thunderx: Fix link status reporting

BugLink: http://bugs.launchpad.net/bugs/1597867

Check for SMU RX local/remote faults along with SPU LINK
status. Otherwise at times link is UP at our end but DOWN
at link partner's side. Also due to an issue in BGX it's
rarely seen that initialization doesn't happen properly
and SMU RX reports faults with everything fine at SPU.
This patch tries to reinitialize LMAC to fix it.

Also fixed LMAC disable sequence to properly bring down link.

iommu/arm-smmu: Workaround for ThunderX erratum #27704

BugLink: http://bugs.launchpad.net/bugs/1590168

Due to erratum #27704, the CN88xx SMMUv2 implementation supports only
shared ASID and VMID numberspaces.

This patch ensures that ASID and VMIDs are unique across all SMMU
instances on affected Cavium systems.

BugLink: http://bugs.launchpad.net/bugs/1589704

The erratum fixes the hang of ITS SYNC command by avoiding inter node
io and collections/cpu mapping on thunderx dual-socket platform.

This fix is only applicable for Cavium's ThunderX dual-socket platform.
