Disabling TSO can cause the dev_watchdog timer to be triggered because
when TSO is disabled netif_tx_stop_all_queues is called. If the watchdog
timer fires while the queues are stopped and traffic has not recently been
sent on a paticular queue this is falsly identified as a hang and
ndo_tx_timeout() is called. This is ocossionally seen during testing.
This removes the netif_tx_stop_all_queues() it is not needed. The scheduler
submits skb's with dev_hard_start_xmit(), this checks if netif_needs_gso and
if so it calls dev_gso_segment. Disabling TSO will cause dev_hard_start_xmit()
to do the gso processing. However ixgbe does not use the features flags to
determine if it needs to use tso or not instead it uses skb->gso_size so
ixgbe will process these frames correctly regardless of the netdev features
flag.

netif_wake_queue() here is wrong. This might cause calling of
start_xmit routine on txfull state and trigger BUG_ON.
This bug does not happen when NAPI disabled. After txdone there
must be at least one free tx slot. But with NAPI, this is not
true anymore and the BUG_ON can hits on heavy load.
In this driver NAPI was enabled on 2.6.33-rc1 so this is
regression from 2.6.32 kernel.

1. Rewrite the outdated help texts for config options ISDN and ISDN_CAPI.

3. HYSDN is not in fact an I4L driver, and needn't depend on ISDN_I4L, so
move it from the I4L section to the general section.

The PowerPC architecture does not require loads to independent bytes to be
ordered without adding an explicit barrier.
In ixgbe_clean_rx_irq we load the status bit then load the packet data.
With packet split disabled if these loads go out of order we get a
stale packet, but we will notice the bad sequence numbers and drop it.
The problem occurs with packet split enabled where the TCP/IP header and data
are in different descriptors. If the reads go out of order we may have data
that doesn't match the TCP/IP header. Since we use hardware checksumming this
bad data is never verified and it makes it all the way to the application.
This bug was found during stress testing and adding this barrier has been shown
to fix it.
