This reverts commit e2ac55b6

.

Huang Ying reports that this causes a hang at boot with debugfs disabled.

It is true that the debugfs error checks are kind of confusing, and this
code certainly merits more cleanup and thinking about it, but there's
something wrong with the trivial "check not just for NULL, but for error
pointers too" patch.

Yes, with debugfs disabled, we will end up setting the o2hb_debug_dir
pointer variable to an error pointer (-ENODEV), and then continue as if
everything was fine.  But since debugfs is disabled, all the _users_ of
that pointer end up being compiled away, so even though the pointer can
not be dereferenced, that's still fine.

So it's confusing and somewhat questionable, but the "more correct"
error checks end up causing more trouble than they fix.

The Error-Bit on the avalon streaming interface of the
tx-dma-channel was always set. In SGMII configurations
this leads to error-symbols on the PCS and packet-rejection
on the receiver side (e.g. SGMII/1000Base-X connected switch).

This only applies to the tse-configuration with MSGDMA.

This issue was detected and fixed on a custom board with
a direct connection to a Marvell switch in SGMII-PHY-Mode.
(incl. custom patches for SGMII-PCS).

According to the datasheet if ff_tx_err (avalon-streaming)
is set it is forwarded to gm_tx_err. As a result the PCS
is forwarding the error by sending a "/V/"-caracter.

====================
net: Fix "hw csum failure" message flood for ppp tunnel

This patch set addresses bug "Bug 95171 - "hw csum failure" message
flood for ppp tunnel since upgrade to 3.16". The problem is that pppoe
is being used over UDP with UDP checksusm enabled. On receive
checksum conversion turns checksum-unnecessary in checksum-
complete. The PPP receive functions do not properly pull
the checksum over its headers, so that when an encapsulated
checksums is considered the checksum-complete value is incorrect.

This patch adds skb_checksum_complete_unset which can be called
in the receive path in lieu of pulling checksum complete in
layer. This is useful when the packet is being modified (e.g.
decompressed) and the checksum-complete value is no longer
relevant.

In the ppp_receive_frame we call skb_checksum_complete_unset to toss
out checksum-complete. This should eliminate the reported messages.
Alternatively, we could add skb_postpull_rcsum and probably
special case handling for VJ compression if maintaining the
checksum-complete is needed (not clear to me this is worth the
effort).

I haven't tested this since setting up the failure scenario doesn't
seem trivial to configure.
