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.

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().

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

This patch makes the private functions alloc_can_skb() and
alloc_can_err_skb() of the at91_can driver public and adapts all
drivers to use these. While making the patch I realized, that
the skb's are *not* setup consistently. It's now done as shown
below:

  skb->protocol = htons(ETH_P_CAN);
  skb->pkt_type = PACKET_BROADCAST;
  skb->ip_summed = CHECKSUM_UNNECESSARY;
  *cf = (struct can_frame *)skb_put(skb, sizeof(struct can_frame));
  memset(*cf, 0, sizeof(struct can_frame));

The frame is zeroed out to avoid uninitialized data to be passed to
user space. Some drivers or library code did not set "pkt_type" or
"ip_summed". Also,  "__constant_htons()" should not be used for
runtime invocations, as pointed out by David Miller.

In order to have better cache layouts of struct sock (separate zones
for rx/tx paths), we need this preliminary patch.

Goal is to transfert fields used at lookup time in the first
read-mostly cache line (inside struct sock_common) and move sk_refcnt
to a separate cache line (only written by rx path)

This patch adds inet_ prefix to daddr, rcv_saddr, dport, num, saddr,
sport and id fields. This allows a future patch to define these
fields as macros, like sk_refcnt, without name clashes.
