Thanks !

[PATCH] atl1c: use custom skb allocator

We had reports ( https://bugzilla.kernel.org/show_bug.cgi?id=54021 )
that using high order pages for skb allocations is problematic for atl1c

We do not know exactly what the problem is, but we suspect that crossing
4K pages is not well supported by this hardware.

Use a custom allocator, using page allocator and 2K fragments for
optimal stack behavior. We might make this allocator generic
in future kernels.

Don't test for having link and let hardware deal with this situation.

Without this patch I see a machine running an -rt patched Linux being
stuck in sch_direct_xmit when it looses link while there is still a
packet to be sent. In this case the fec_enet_start_xmit routine returned
NETDEV_TX_BUSY which makes the network stack reschedule the packet and
so sch_direct_xmit calls fec_enet_start_xmit again.
I failed to reproduce a complete hang without -rt, but I think the
problem exists there, too.

This patch fixes a VT mode check to make sure VLAN filters are disabled when
in promisc mode and VT is not enabled.

The problem with the previous check was that:
E1000_MRQC_ENABLE_VMDQ is defined as 0x00000003

but when not in VT mode:
mrqc |= E1000_MRQC_ENABLE_RSS_4Q (0x00000002)

So the above check will trigger regardless if VT mode is being used or not.

If the ready bit in the transmit buffer descriptor (TxBD[R])
is previously detected as not set during a prior frame transmission,
then the ENET_TDAR[TDAR] bit is cleared at a later time, even if
additional TxBDs were added to the ring and the ENET_TDAR[TDAR]
bit is set. This results in frames not being transmitted until
there is a 0-to-1 transition on ENET_TDAR[TDAR].

Workarounds:
code can use the transmit frame interrupt flag (ENET_EIR[TXF])
as a method to detect whether the ENET has completed transmission
and the ENET_TDAR[TDAR] has been cleared. If ENET_TDAR[TDAR] is
detected as cleared when packets are queued and waiting for transmit,
then a write to the TDAR bit will restart TxBD processing.

This case main happen when loading is light. A ethernet package may
not send out utile next package put into tx queue.

How to test:
while [ true ]
do
	ping <IP> -s 10000 -w 4
	ping <IP> -s 6000 -w 2
	ping <IP> -s 4000 -w 2
	ping <IP> -s 10000 -w 2
done

You will see below result in overnight test.

atl1c uses netdev_alloc_skb to refill its rx dma ring, but that call makes no
guarantees about the suitability of the memory for use in DMA.  As a result
we've gotten reports of atl1c drivers occasionally hanging and needing to be
reset:
https://bugzilla.kernel.org/show_bug.cgi?id=54021

Fix this by modifying the call to use the internal version __netdev_alloc_skb,
where you can set the gfp_mask explicitly to include GFP_DMA.

The work queue is initialised in rtl_open (when the interface goes up),
but canceled in rtl_remove_one (when the PCI device gets removed). If
the network interface is not brought up, then the work queue struct is
not initialised. When the device is removed, the attempt to cancel the
uninitialised work queue causes a lockdep warning.

This patch fixes the issue by moving cancel_work_sync to rtl_close (to
match rtl_open). (Note that rtl_close is also called via
unregister_netdev in rtl_remove_one.)
