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.

Fix race conditions in mrf24j40 interrupts

After testing with the betas of this patchset, it's been rebased and is
ready for inclusion.

David Hauweele noticed that the mrf24j40 would hang arbitrarily after some
period of heavy traffic.  Two race conditions were discovered, and the
driver was changed to use threaded interrupts, since the enable/disable of
interrupts in the driver has recently been a lighning rod whenever issues
arise related to interrupts (costing engineering time), and since threaded
interrupts are the right way to do it.
====================

The mrf24j40 generates level interrupts. There are rare cases where it
appears that the interrupt line never gets de-asserted between interrupts,
causing interrupts to be lost, and causing a hung device from the driver's
perspective.  Switching the driver to interpret these interrupts as
level-triggered fixes this issue.

The (inner) MTU of a ipip6 (IPv4-in-IPv6) tunnel cannot be set below 1280, which is the minimum MTU in IPv6.
However, there should be no IPv6 on the tunnel interface at all, so the IPv6 rules should not apply.
More info at https://bugzilla.kernel.org/show_bug.cgi?id=15530

This patch allows to check the minimum MTU for ipv6 tunnel according to these rules:
-In case the tunnel is configured with ipip6 mode the minimum MTU is 68.
-In case the tunnel is configured with ip6ip6 or any mode the minimum MTU is 1280.

Yuchung found following problem :

 There are bugs in the SACK processing code, merging part in
 tcp_shift_skb_data(), that incorrectly resets or ignores the sacked
 skbs FIN flag. When a receiver first SACK the FIN sequence, and later
 throw away ofo queue (e.g., sack-reneging), the sender will stop
 retransmitting the FIN flag, and hangs forever.

Following packetdrill test can be used to reproduce the bug.

$ cat sack-merge-bug.pkt
`sysctl -q net.ipv4.tcp_fack=0`

// Establish a connection and send 10 MSS.
0.000 socket(..., SOCK_STREAM, IPPROTO_TCP) = 3

First, a typo inverted left/right of one OR operation, then
code forgot to advance end_seq if the merged skb carried FIN.

Sebastian Hesselbarth says:

====================
This patch set comprises some one-liners to fix issues with repeated
loading and unloading of a modular mv643xx_eth driver.

First two patches take care of the periodic port statistic timer, that
updates statistics by reading port registers using add_timer/mod_timer.

Patch 1 moves timer re-schedule from mib_counters_update to the timer
callback. As mib_counters_update is also called from non-timer context,
this ensures the timer is reactivated from timer context only.

Patch 2 moves initial timer schedule from _probe() time to right before
the port is actually started as the corresponding del_timer_sync is at
_stop() time. This fixes a regression, where unloading the driver from a
non-started eth device can cause the timer to access deallocated mem.

Patch 3 adds an assignment of the ports device_node to the corresponding
self-created platform_device. This is required to allow fixups based on
the device_node's compatible string later. Actually, it is also a potential
regression because we already check compatible string for Kirkwood, but
does not (yet) rely on the fixup.

All patches are based on v3.12-rc3 and have been tested on Kirkwood-based
Seagate Dockstar.

Patches 1 and 2 can also possibly queued up for -stable.

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.

commit 3ab5aee7 ("net: Convert TCP & DCCP hash tables to use RCU /
hlist_nulls") incorrectly used sock_put() on TIMEWAIT sockets.

We should instead use inet_twsk_put()

tcp_established_options assumes opts->options is 0 before calling,
as it read modify writes it.

For the tcp_current_mss() case the opts structure is not zeroed,
so this can be done with uninitialized values.

This is ok, because ->options is not read in this path.
But it's still better to avoid the operation on the uninitialized
field. This shuts up a static code analyzer, and presumably
may help the optimizer.

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
and detect the number of filter registers at run-time. Unfortunately,
the version register is the same on both SOCs, so simply test if write to
the last filter register will take a value. It always reads as 0 if not.

Even in promiscuous mode, we need to add filter addresses for correct
operation. This fixes silent failures when using a bridge and adding
addresses using the "bridge fdb add" command.

In commit 2ee68f62 (net: calxedaxgmac: fix various errors in
xgmac_set_rx_mode), a fix to clean-up old address entries was added.
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 <.
