Enable workaround for P2020/P2010 erratum eTSEC 20,
"Excess delays when transmitting TOE=1 large frames".
The impact is that frames lager than 2500-bytes for which
TOE (i.e. TCP/IP hw accelerations like Tx csum) is enabled
may see excess delay before start of transmission.
This erratum was fixed in Rev 2.0.

Use the macros and defines from mpc85xx.h to simplify
and prevent errors in identifying a mpc85xx based SoC
for errata detection.
This should help enabling (and identifying) workarounds
for various mpc85xx based chips and revisions.
For instance, express MPC8548 Rev.2 as:
(SVR_SOC_VER(svr) == SVR_8548) && (SVR_REV(svr) == 0x20)
instead of:
(pvr == 0x80210020 && mod == 0x8030 && rev == 0x0020)

A002 is still in "no plans to fix" state, and applies to all
the current P1/P2 parts as well, so it's resonable to enable
its workaround by default, for all the soc's with etsec.
The impact of not enabling this workaround for affected parts
is that under certain conditons (runt frames or even frames
with RX error detected at PHY level) during controller reset,
the controller might fail to indicate Rx reset (GRS) completion.

Ben Hutchings says:
====================
Some more fixes for EF10 support; hopefully the last lot:
1. Fixes for reading statistics, from Edward Cree and Jon Cooper.
2. Addition of ethtool statistics for packets dropped by the hardware
before they were associated with a specific function, from Edward Cree.
3. Only bind to functions that are in control of their associated port,
as the driver currently assumes this is the case.

This patch fixes a bug introduced by commit 51151a16 (mlx4: allow
order-0 memory allocations in RX path).
dma_unmap_page never reached because condition to detect last fragment
in page is wrong. offset+frag_stride can't be greater than size, need to
make sure no additional frag will fit in page => compare offset +
frag_stride + next_frag_size instead.
next_frag_size is the same as the current one, since page is shared only
with frags of the same size.

This patch will fix RX packets errors when receiving big size
of data by set bit RNC = 1.
RNC - Receive Enable Control
0: Upon completion of reception of one frame, the E-DMAC writes
the receive status to the descriptor and clears the RR bit in
EDRRR to 0.
1: Upon completion of reception of one frame, the E-DMAC writes
(writes back) the receive status to the descriptor. In addition,
the E-DMAC reads the next descriptor and prepares for reception
of the next frame.
In addition, for get more stable when receiving packets, I set
maximum size for the transmit/receive FIFO and inserts padding
in receive data.

Although we do not yet enable multiple PFs per port, it is possible
that a board will be reconfigured to enable them while the driver has
not yet been updated to fully support this.
The most obvious problem is that multiple functions may try to set
conflicting link settings. But we will also run into trouble if the
firmware doesn't consider us fully trusted. So, abort probing unless
both the LinkCtrl and Trusted flags are set for this function.

Recognise the new Packet Memory and RX Data Path counters.
The following counters are added:
rx_pm_{trunc,discard}_bb_overflow - burst buffer overflowed. This should not
occur if BB correctly configured.
rx_pm_{trunc,discard}_vfifo_full - not enough space in packet memory. May
indicate RX performance problems.
rx_pm_{trunc,discard}_qbb - dropped by 802.1Qbb early discard mechanism.
Since Qbb is not supported at present, this should not occur.
rx_pm_discard_mapping - 802.1p priority configured to be dropped. This should
not occur in normal operation.
rx_dp_q_disabled_packets - packet was to be delivered to a queue but queue is
disabled. May indicate misconfiguration by the driver.
rx_dp_di_dropped_packets - parser-dispatcher indicated that a packet should be
dropped.
rx_dp_streaming_packets - packet was sent to the RXDP streaming bus, ie. a
filter directed the packet to the MCPU.
rx_dp_emerg_{fetch,wait} - RX datapath had to wait for descriptors to be
loaded. Indicates performance problems but not drops.
These are only provided if the MC firmware has the
PM_AND_RXDP_COUNTERS capability. Otherwise, mask them out.

Previously, efx_ef10_stat_mask returned a static const unsigned long[], which
meant that each possible mask had to be declared statically with
STAT_MASK_BITMAP. Since adding a condition would double the size of the
decision tree, we now create the bitmask dynamically.
To do this, we have two functions efx_ef10_raw_stat_mask, which returns a u64,
and efx_ef10_get_stat_mask, which fills in an unsigned long * argument.

This patch allows (optionally, via ethtool) the atl1e NIC to:
- Receive bad frames (runt, bad-fcs, etc..)
- Receive full frames without stripping the FCS.
This has been tested on my board by injecting runt and bad-fcs
frames with a FPGA-based device.
The particular scenario of receiving very short frames (<4 bytes)
without passing FCS to the upper layer has been also tested:
This could be potentially dangerous because the driver performs a
4 byte subtraction on the frame length, but I finally have NOT
added anything to avoid this because it seems the NIC always
discards frames so much short..
If someone still have some reason to worry about this, please
tell me.. I will add an explicit SW check..

The periodic statistics timer gets started at port _probe() time, but
is stopped on _stop() only. In a modular environment, this can cause
the timer to access already deallocated memory, if the module is unloaded
without starting the eth device. To fix this, we add the timer right
before the port is started, instead of at _probe() time.

eee_get_cur assumes that the output data is already zeroed. It can
read-modify-write the advertised field:
if (ipcnfg & E1000_IPCNFG_EEE_100M_AN)
2594 edata->advertised |= ADVERTISED_100baseT_Full;
This is ok for the normal ethtool eee_get call, which always
zeroes the input data before.
But eee_set_cur also calls eee_get_cur and it did not zero the input
field. Later on it then compares agsinst the field, which can contain partial
stack garbage.
Zero the input field in eee_set_cur() too.

Highbank and Midway xgmac h/w have different number of MAC address filter
registers with 7 and 31, respectively. Highbank has been wrong, so fix it

However, the loop to zero out the entries failed to increment the register
address resulting in only 1 entry getting cleared. Fix this to correctly
use the loop index. Also, the end of the loop condition was off by 1 and
should have been <= rather than <.
