With durations less than 20ms, the jiffies or legacy timer backed msleep()
may sleep ~20ms which might not be what the caller expects.  Instead, it
is recommended to use the hrtimers backed usleep_range().  For more, see
Documentation/timers/timers-howto.txt.  Issues reported by checkpatch.

In addition, remove unnecessary sleep in e1000e_write_nvm_spi().

In some devices, the VPD block is relocated to a different area in
NVRAM.  The original location can still contain old, but still valid VPD
data.  This patch changes the code to look for an extended VPD block in
NVRAM.  If one is found, that block is used for all VPD operations
instead.

The "iavcc" and "iadev" cases are obvious.

The intr_status and frmr_intr cases are reading a register to clear
the chip status.  This driver is pretty old and creaky, and uses
volatile pointer dereferences to do register I/O when it should be
using readl() and friends.  However that it outside of the scope of
these changes.

Now there are 2 paths for rx vlan frames. When rx-vlan-hw-accel is
enabled, skb is untagged by NIC, vlan_tci is set and the skb gets into
vlan code in __netif_receive_skb - vlan_hwaccel_do_receive.

For non-rx-vlan-hw-accel however, tagged skb goes thru whole
__netif_receive_skb, it's untagged in ptype_base hander and reinjected

This incosistency is fixed by this patch. Vlan untagging happens early in
__netif_receive_skb so the rest of code (ptype_all handlers, rx_handlers)
see the skb like it was untagged by hw.

Most of these are cases where we are trying to read back a register
after a write to ensure completion.

Simply pre-fixing the readl() or readq() with "(void)" is sufficient
because these are volatile operations and the compiler cannot eliminate
them just because no real assignment takes place.

The case of free_rxd_blk()'s assignments to "struct buffAdd *ba" is a
real spurious assignment as this variable is completely otherwise
unused.

When the RX network flow classification interface was originally
defined for reporting and controlling of flow hashing, AH and ESP were
not given distinct flow class codes (apparently because the Sun
Neptune hardware treats them very similarly).

For flow steering, they must be distinguished, so new and separate
flow class codes were added for AH and ESP.  But for backward-
compatibility, flow hash operations should continue to support the
original class codes.

This code was cribbed from niu, so gfar_set_hash_opts() begins by
