91cc3bb0b0 xfrm6_tunnel: RCU conversion
xfrm6_tunnels use one rwlock to protect their hash tables.

Plain and straightforward conversion to RCU locking to permit better SMP
performance.

4543c10de2 ipv6 sit: RCU conversion phase II
SIT tunnels use one rwlock to protect their hash tables.

This locking scheme can be converted to RCU for free, since netdevice
already must wait for a RCU grace period at dismantle time.

ef9a9d1183 ipv6 sit: RCU conversion phase I
SIT tunnels use one rwlock to protect their prl entries.

This first patch adds RCU locking for prl management,
with standard call_rcu() calls.

b37b62fea1 sfc: Rename 'xfp' file and functions to reflect reality
The 'XFP' driver is really a driver for the QT2022C2 and QT2025C PHYs,
covering both more and less than XFP.  Rename its functions and
constants to reflect reality and to reduce namespace pollution when
sfc is a built-in driver.

a5211bb5f7 sfc: Move MTD probe after netdev registration and name allocation
The MTD partition is named based on the netdev name, which is set to
'eth%d' before registration.  Also, the MTD partition will currently
be left registered if netdev registration fails.

Fix both these problems by moving the MTD probe after netdev
registration.  Hold the RTNL to serialise this with the netdev
notifier that calls efx_mtd_rename().

3e6c453854 sfc: Update hardware definitions for Siena
Siena is still based on the Falcon hardware architecture and will
share many of these definitions, so replace falcon_hwdefs.h with
regs.h.

The new definitions have been generated according to a naming
convention which incorporates the type and revision information.
Update the code accordingly.

56241ceb9e sfc: Remove versioned bitfield macros
These macros are not extensible to more than two NIC types without
repetition of register definitions, and they are only used to deal
with a few fields in RX_CFG_REG and global events which moved between
Falcon rev A1 and B0.

Therefore:
- Move RX_CFG_REG initialisation into its own function which tests the
  NIC revision just once
- Explicitly test the NIC revision when checking the RX_RECOVERY flag in
  global events
- Merge definitions of RX_XOFF_MAC_EN flag, which did not move
- Remove the macro definitions
