The commit 6494294f27 ("i40e/i40evf: Use
dma_set_mask_and_coherent") uses dma_set_mask_and_coherent() to
replace dma_set_coherent_mask() for the benefit of return error.
The conversion brings some confusion in error checking as whether
against DMA_BIT_MASK(64) or DMA_BIT_MASK(32). For one, if error is
zero, the check will be against DMA_BIT_MASK(64) twice. Fix this
error checking by binding the check to the pertinent one.

In commit da1e2046e5, the flow for enabling/disabling an Si errata
workaround (e1000_lv_jumbo_workaround_ich8lan) was changed to fix a problem
with iAMT connections dropping on interface down with jumbo frames set.
Part of this change was to move the function call disabling the workaround
to e1000e_down() from the e1000_setup_rctl() function. The mechanic for
disabling of this workaround involves writing several MAC and PHY registers
back to hardware defaults.
After this commit, when the driver is loaded with the cable out, the PHY
registers are not programmed with the correct default values. This causes
the device to be capable of transmitting packets, but is unable to recieve
them until this workaround is called.
The flow of e1000e's open code relies upon calling the above workaround to
expicitly program these registers either with jumbo frame appropriate settings
or h/w defaults on 82579 and newer hardware.
Fix this issue by adding logic to e1000_setup_rctl() that not only calls
e1000_lv_jumbo_workaround_ich8lan() when jumbo frames are set, to enable the
workaround, but also calls this function to explicitly disable the workaround
in the case that jumbo frames are not set.

In rtl8180/rtl8185/rtl8187se the register space is represented
using packed structure type. Register are thus accessed using a
pointer of this type.
All registers are packed toghether, and only small gaps are present.
However Rtl8187se has also some "sparse" registers, very far from
the "main register block".
It could be possible to access them by simply declare huge reserved
blocks inside the register struct (and this causes NO memory waste).
However, for various reasons, access to those "far" registers is
done with special dedicated macros, without declaring them in the
register struct.
This is done in an intricate manner, that makes code less readable
and caused static analisys tool to produce warnings.
This patch keeps the "macro" mechanism, but it changes its
implementation in a simplier and more straightforward way.

There are currently pch_gbe, cpts, and ixp4xx_eth drivers that open-code
and reimplement a BPF classifier for the PTP protocol. Since all of them
effectively do the very same thing and load the very same PTP/BPF filter,
we can just consolidate that code by introducing ptp_classify_raw() in
the time-stamping core framework which can be used in drivers.
As drivers get initialized after bootstrapping the core networking
subsystem, they can make use of ptp_insns wrapped through
ptp_classify_raw(), which allows to simplify and remove PTP classifier
setup code in drivers.

The worse-case estimate for skb ring slot usage in xenvif_rx_action()
fails to take fragment page_offset into account. The page_offset does,
however, affect the number of times the fragmentation code calls
start_new_rx_buffer() (i.e. consume another slot) and the worse-case
should assume that will always return true. This patch adds the page_offset
into the DIV_ROUND_UP for each frag.
Unfortunately some frontends aggressively limit the number of requests
they post into the shared ring so to avoid an estimate that is 'too'
pessimal it is capped at MAX_SKB_FRAGS.

The mvneta driver currently uses of_iomap(), which has two drawbacks:
it doesn't request the resource, and it isn't devm-style so some error
handling is needed.
This commit switches to use devm_ioremap_resource() instead, which
automatically requests the resource (so the I/O registers region shows
up properly in /proc/iomem), and also is devm-style, which allows to
get rid of some error handling to unmap the I/O registers region.
