Change sfn4111t_reset() to change only GPIO output enables so that it
doesn't break subsequent I2C operations.
Update comments to explain exactly what we're doing.
Add a short sleep to make sure the FLASH_CFG_1 value is latched before
any subsequent I2C operations.

Early versions of the SFX7101 firmware could complete link training in
a state where it would not adequately cancel noise (Solarflare bug
10750). We previously worked around this by resetting the PHY after
seeing many Ethernet CRC errors. This workaround is unsafe since it
takes no account of the interval between errors; it also appears to
be unnecessary with production firmware. Therefore remove it.

commit 0f0ca340e5 ("phy: power
management support") caused a regression in the gianfar driver.
Now phylib turns off PHY power during suspend, and thus WOL
doesn't work anymore.
This patch workarounds the issue by enabling wakeup in the MDIO
device, i.e. just restores the old behaviour for the gianfar
driver. Note that this way all PHYs on a given MDIO bus won't
be turned off during suspend, which isn't good from the power
saving point of view.
A proper, per netdevice wakeup management support will need
a bit reworked phylib suspend/resume logic.

smsc9420 performs an interrupt signalling test when the interface is
brought up. The current code mistakenly sets its test flag to false
AFTER enabling the software interrupt source, making failure quite
likely.
This patch changes the code to set the test flag BEFORE enabling
interrupts. I've also removed an smp_wmb because the following spinlock
provides an implicit memory barrier.

The commit b31a1d8b41 ("gianfar: Convert
gianfar to an of_platform_driver") changes the gianfar's phy id to the
format like "mdio@xxxx:xx", but uec still uses the old format like
"xxxxxxxx:xx". For the board whose UEC uses gianfar-mdio like
MPC8568MDS, the phy can not be attached because of the incompatible
phy id format. This patch changes uec's phy id to the same format as
gianfar's.

The definitions needed for the wimax stack and i2400m driver debug
infrastructure was, by mistake, compiled depending on CONFIG_DEBUG_FS
(by them being placed in the debugfs.c files); thus the build broke in
2.6.29-rc3 when debugging was enabled (CONFIG_WIMAX_DEBUG) and
DEBUG_FS was disabled.
These definitions are always needed if debug is enabled at compile
time (independently of DEBUG_FS being or not enabled), so moving them
to a file that is always compiled fixes the issue.

It oopsd for me in skb_seq_read. addr2line said it was
linux-2.6/net/core/skbuff.c:2228, which is this line:
while (st->frag_idx < skb_shinfo(st->cur_skb)->nr_frags) {
I added some printks in there and it looks like we hit this:
} else if (st->root_skb == st->cur_skb &&
skb_shinfo(st->root_skb)->frag_list) {
st->cur_skb = skb_shinfo(st->root_skb)->frag_list;
st->frag_idx = 0;
goto next_skb;
}
Actually I did some testing and added a few printks and found that the
st->cur_skb->data was 0 and hence the ptr used by iscsi_tcp was null.
This caused the kernel panic.
if (abs_offset < block_limit) {
- *data = st->cur_skb->data + abs_offset;
+ *data = st->cur_skb->data + (abs_offset - st->stepped_offset);
I enabled the debug_tcp and with a few printks found that the code did
not go to the next_skb label and could find that the sequence being
followed was this -
It hit this if condition -
if (st->cur_skb->next) {
st->cur_skb = st->cur_skb->next;
st->frag_idx = 0;
goto next_skb;
And so, now the st pointer is shifted to the next skb whereas actually
it should have hit the second else if first since the data is in the
frag_list.
else if (st->root_skb == st->cur_skb &&
skb_shinfo(st->root_skb)->frag_list) {
st->cur_skb = skb_shinfo(st->root_skb)->frag_list;
goto next_skb;
}
Reversing the two conditions the attached patch fixes the issue for me
on top of Herbert's patches.

The frag_list handling was broken in skb_seq_read:
1) We didn't add the stepped offset when looking at the head
are of fragments other than the first.
2) We didn't take the stepped offset away when setting the data
pointer in the head area.
3) The frag index wasn't reset.
This patch fixes both issues.

Reducing jumbo ring size below 1024 reduces throughput for old
firmwares (3.4.216 and older) running on older (NX2031) chip,
so restore it back to 1024.
This was reduced in commit 32ec803348
("netxen: reduce memory footprint").
Raising jumbo ring size from 512 to 1024, adds ~4MB per port, but
there's still big saving because of original patch (~20MB per port).

After reports of poor performance, a review of the latest vendor driver
(rtl8187_linux_26.1025.0328.2007) for RTL8187L devices was undertaken.
A difference was found in the code used to index the OFDM power tables. When
the Linux driver was changed, my unit works at a much greater range than
before. I think this fixes Bugzilla #12380 and has been tested by at least
two other users.
