This reverts commit f83331bab149e29fa2c49cf102c0cd8c3f1ce9f9.
As the tests PPC64 (powernv platform) show, IOMMU pages are leaking
when transferring big amount of small packets (<=64 bytes),
"ping -f" and waiting for 15 seconds is the simplest way to confirm the bug.

It is possible for some versions of firmware to advertise capabilities that driver
is not ready to handle. This may lead to controller stall. Since the driver is
interested only in subset of flags, clearing the rest.

Initially I improperly set a boundary for maximum number of input
packets to process on NAPI poll ("work") so it might be more than
expected amount ("weight").
This was really harmless but seeing WARN_ON_ONCE on every device boot is
not nice. So trivial fix ("<" instead of "<=") is here.

There might be a crash as during shutdown flow CNIC might try
to access resources already freed by bnx2x.

John W. Linville says:
====================
This is a batch of updates intended for 3.12. It is mostly driver
stuff, although Johannes Berg and Simon Wunderlich make a good
showing with mac80211 bits (particularly some work on 5/10 MHz
channel support).
The usual suspects are mostly represented. There are lots of updates
to iwlwifi, ath9k, ath10k, mwifiex, rt2x00, wil6210, as usual.
The bcma bus gets some love this time, as do cw1200, iwl4965, and a
few other bits here and there. I don't think there is much unusual
here, FWIW.

eTSEC has Rx and Tx flow control capabilities that may be enabled
through MACCFG1[Rx_Flow, Tx_Flow] bits. These bits must not be set
however when eTSEC is operated in Half-Duplex mode. Unfortunately,
the driver currently sets these bits unconditionally.
This patch adds the proper handling of the PAUSE frame capability
register bits by implementing the ethtool -A interface. When pause
autoneg is enabled, the controller uses the phy's capability to
negotiate PAUSE frame settings with the link partner and reconfigures
its Rx_Flow and Tx_Flow settings to match the capabilities of the
link partner. If pause autoneg is off, the PAUSE frame generation
may be forced manually (ethtool -A). Flow control is disabled by
default now.
This implementation is inspired by the tg3 driver.

The Compressed LIP region is used to hold a limited number of Local
IPv6 addresses. This region is primarily used to reduce the TCAM
space consumed for an IPv6 offloaded connection. A 128-bit LIP will
be reduced to 13-bit and stored in the TCAM if there is a match
between the IPv6 tuple's LIP and the one stored in the CLIP region.

Add cxgb4_create_server6 and cxgb4_remove_server routines to create
and remove listening IPv6 servers.
Return success (0) from cxgb4_create_server in case of ctrl queue
congestion since in case of congestion, passive open request gets
queued and gets processed later. If a non-zero value were returned it
would be treated as an error and the ULD would free STID, which can
result in an error in passive open reply.

Cleanup gfar_start_xmit()'s fast path by factoring out "redundant"
FCB insertion code (repeated gfar_add_fcb() calls and related)
and by reducing the number of if() clauses (i.e. if(fcb) checks).
Improve maintainability (e.g. there's less code and easier to read)
also by introducing do_csum and do_vlan to mark the other 2 Tx TOE
functionalities, following the same model as do_tstamp.
fcb_len may also be 0 now, to mark that Tx FCB insertion conditions
(do_csum, do_vlan, do_tstamp) have not been met.

Both [eTSEC76] and [eTSEC12] errata relate to Tx checksum generation
(for some MPC83xx and MCP8548 older revisions). They require the same
workaround: manual checksum computation and insertion, and disabling
the H/W Tx csum acceleration feature (per frame) through Tx FCB
(Frame Control Block) csum offload settings.
The workaround for [eTSEC76] needs to be fixed because it currently
fails to disable H/W Tx csum insertion via FCB. This patch fixes it
and provides a common workaround implementation for both Tx csum errata.
