When tg3 was new, phy accesses through ioctl were allowable at any time.
Then, the driver started shutting down the phy when the device was
closed.  Phy accesses would be allowed when the driver first attached to
the device, but then would be forbidden after the device had been up'd
and down'd.  After that, management firmware made it illegal to access
the phy unless the driver "owned" the device.  Now that most firmware
is being moved over to the APE, it is less clear when phy accesses are
safe.

While it is possible to attempt to identify these conditions and code
the driver to navigate through the pitfalls, it could be perplexing to
the admin why phy accesses work in some cases and not others.  This
patch brings some uniformity to the problem by only allowing phy
accesses while the driver has control of the device.

The loopback test assumes all traffic goes to the first rx queue.  There
is a 1 in 4 chance this won't be true if RSS is enabled though.  This

The oldest tg3 devices had large rx producer ring BD caches.  Back then,
it made sense to make the BD cache replenish threshold only a function
of the number of rx buffers posted by the driver.  Since then, the BD
cache sizes have shrunk to 25% of their original size and, in some
cases, the ring sizes have quadrupled in size.  Under such conditions,
static BD cache replenish thresholds no longer match the hardware
constraints.

This patch attempts to factor in the BD cache size into the bd cache
replenish strategy, taking the existing hardware bugs into account.

The 5717, 5718, 5719 A0, and 5720 A0 has a bug where the rx_discards
statistic counter will increment when dropping unwanted multicast

recreate the data using other means.  The resulting value will not be
accurate, but it can still serve as a problem indicator.

This changes offload setting behaviour to what I think is correct:
 - offloads set via ethtool mean what admin wants to use (by default
   he wants 'em all)
 - offloads set via ioctl() mean what userspace is expecting to get
   (this limits which admin wishes are granted)
 - TUN_NOCHECKSUM is ignored, as it might cause broken packets when
   forwarded (ip_summed == CHECKSUM_UNNECESSARY means that checksum
   was verified, not that it can be ignored)

If TUN_NOCHECKSUM is implemented, it should set skb->csum_* and
skb->ip_summed (= CHECKSUM_PARTIAL) for known protocols and let others
be verified by kernel when necessary.

TUN_NOCHECKSUM handling was introduced by commit
f43798c2:

- the MSS value is actually contained in a 11 bits wide (0x7ff) field.
  The extra bit in the former MSSMask did encompass the TSO command
  bit ("LargeSend") as well (0xfff). Oops.

- the Tx descriptor layout is not the same through the whole chipset
  family. The 8169 documentation, the 8168c documentation and Realtek's
  drivers (8.020.00, 1.019.00, 6.014.00) highlight two layouts:
  1. 8169, 8168 up to 8168b (included) and 8101
  2. {8102e, 8168c} and beyond

- notwithstanding the "first descriptor" and "last descriptor" bits, the
  same Tx descriptor content is enforced when a packet consists of several
  descriptors. The chipsets are documented to require it.

Several tests in the ipv6 routing code check IFF_LOOPBACK, and
allowing stacking such as VLAN'ing on top of loopback results in a
netdevice which reports IFF_LOOPBACK but really isn't the loopback
device.

Instead of spamming the ipv6 routing code with even more special tests,
simply disallow VLAN over loopback.
