The ixgbe_down function can now prevent multiple executions by
doing test_and_set_bit on __IXGBE_DOWN. This did not work before
introduction of the __IXGBE_REMOVING bit, because of overloading
of __IXGBE_DOWN. Also add smp_mb__before_clear_bit call before
clearing the __IXGBE_DOWN bit.

Add a bit, __IXGBE_REMOVING, to indicate that the module is being
removed. The __IXGBE_DOWN bit had been overloaded for this purpose,
but that leads to trouble. A few places now check both __IXGBE_DOWN
and __IXGBE_REMOVE. Notably, setting either bit will prevent service
task execution.

sh_eth_error() in case of a TX error tries to print a message using 2 dev_err()
calls with the first string not finished by '\n', so that the resulting message
would inevitably come out garbled, with something like "3net eth0: " inserted
in the middle.  Avoid that by merging 2 calls into one.

While at it, insert an empty line after the nearby declaration.

found by running 'make namespacecheck'

 * global variables must be prefixed with bnx2x_
    naming a variable int_mode, or num_queue is invitation to disaster

 * make local functions static

 * move some inline's used in one file out of header
   (this driver has a bad case of inline-itis)

 * remove resulting dead code fallout
 	 bnx2x_pfc_statistic,
	 bnx2x_emac_get_pfc_stat
 	 bnx2x_init_vlan_mac_obj,

In order to use the native GRO handling of encapsulated protocols on
mlx4, we need to call napi_gro_receive() instead of netif_receive_skb()
unless busy polling is in action.

While we are at it, rename mlx4_en_cq_ll_polling() to
mlx4_en_cq_busy_polling()
