Originally there were several implementations of PHY operations for the
several different PHYs used on Falcon boards. But Falcon is now in a
separate driver, and all sfc NICs since then have had MCDI-managed PHYs.
Thus, there is no need to indirect through function pointers in
efx->phy_op; we can simply call the efx_mcdi_phy_* functions directly.
This also hooks up these functions for EF100, which was previously using
the dummy_phy_ops.

bnxt_fw_reset_task() which runs from a workqueue can race with
bnxt_remove_one(). For example, if firmware reset and VF FLR are
happening at about the same time.
bnxt_remove_one() already cancels the workqueue and waits for it
to finish, but we need to do this earlier before the devlink
reporters are destroyed. This will guarantee that
the devlink reporters will always be valid when bnxt_fw_reset_task()
is still running.

When the driver goes through PCIe AER reset in error state, all
firmware messages will timeout because the PCIe bus is no longer
accessible. This can lead to AER reset taking many minutes to
complete as each firmware command takes time to timeout.
Define a new macro BNXT_NO_FW_ACCESS() to skip these firmware messages
when either firmware is in fatal error state or when
pci_channel_offline() is true. It now takes a more reasonable 20 to
30 seconds to complete AER recovery.

The wrappers in include/linux/pci-dma-compat.h should go away.
The patch has been generated with the coccinelle script below and has been
hand modified to replace GFP_ with a correct flag.
It has been compile tested.
When memory is allocated in 'vnic_dev_classifier()', 'vnic_dev_fw_info()',
'vnic_dev_notify_set()' and 'vnic_dev_stats_dump()' (vnic_dev.c) GFP_ATOMIC
must be used because its callers take a spinlock before calling these
functions.
When memory is allocated in '__enic_set_rsskey()' and 'enic_set_rsscpu()'
GFP_ATOMIC must be used because they can be called with a spinlock.
The call chain is:
enic_reset <-- takes 'enic->enic_api_lock'
--> enic_set_rss_nic_cfg
--> enic_set_rsskey
--> __enic_set_rsskey <-- uses dma_alloc_coherent
--> enic_set_rsscpu <-- uses dma_alloc_coherent
When memory is allocated in 'vnic_dev_init_prov2()' GFP_ATOMIC must be used
because a spinlock is hidden in the ENIC_DEVCMD_PROXY_BY_INDEX macro, when
this function is called in 'enic_set_port_profile()'.
When memory is allocated in 'vnic_dev_alloc_desc_ring()' GFP_KERNEL can be
used because it is only called from 5 functions ('vnic_dev_init_devcmd2()',
'vnic_cq_alloc()', 'vnic_rq_alloc()', 'vnic_wq_alloc()' and
'enic_wq_devcmd2_alloc()'.
'vnic_dev_init_devcmd2()': already uses GFP_KERNEL and no lock is taken
in the between.
'enic_wq_devcmd2_alloc()': is called from ' vnic_dev_init_devcmd2()'
which already uses GFP_KERNEL and no lock is taken in the between.
'vnic_cq_alloc()', 'vnic_rq_alloc()', 'vnic_wq_alloc()': are called
from 'enic_alloc_vnic_resources()'
'enic_alloc_vnic_resources()' has only 2 call chains:
1) enic_probe
--> enic_dev_init
--> enic_alloc_vnic_resources
'enic_probe()' is a probe function and no lock is taken in the between
2) enic_set_ringparam
--> enic_alloc_vnic_resources
'enic_set_ringparam()' is a .set_ringparam function (see struct
ethtool_ops). It seems to only take a mutex and no spinlock.
So all paths are safe to use GFP_KERNEL.

We unconditionally set tx_queue->xmit_pending (renamed from

efx_tx_send_pending(), which will clear xmit_pending. Thus, after an
