Some versions of the Marvell yukon generate bogus sensor warning interrupts.
The driver would flood log with these messages. Handle this situation
cleanly by masking away at boot time.

IEEE 802.11 has a capability field flag called ESS, but ieee80211 had
renamed this to BSS for some reason. hostap has been using
WLAN_CAPABILITY_ESS and since that matches with the standard, lets use
it as the name for this define. Add WLAN_CAPABILITY_BSS as a backwards
compatibility name for the same bit since ieee80211 and ipw2200 are
using this and there are versions outside kernel tree that expect to
find this define name.

Replace hardware model specific #ifdef's in struct local_info with
void *hw_priv that is pointing to cs/pci/plx specific data
structure. This removes unneeded #ifdef's and as such, is a step
towards making it possible to share objects for hostap_hw.c and
hostap_download.c with cs/pci/plx drivers without having to compile
and link the same code separately for each one.

PCI version of Prism2.5/3 has undocumented DMA support for TX/RX data,
but this seems to have some hardware bugs that prevent it from being
used properly for TX. RX side could possibly be made to work reliably.
Even though DMA support would be very useful for saving host CPU (from
about 40% to 5-10% when operating at maximum throughput), it seems to
be best to just remove this code finally. The implementation has
always been commented out by default and has received very limited
testing. The code may have already been broken number of times and I
don't have much interested in trying to verify whether it works or
not. Getting this out makes it easier to maintain the driver and
allows some cleanups that have been partly postponed because of this
experimental bus master/DMA code.

Old AP mode code for power saving was using skb->cb for couple of
flags before the more generic 802.11 TX code started using the same
buffer for struct hostap_skb_tx_data. This resulted in the power save
code corrupting the magic value in beginning of the buffer and TX code
dropping the power saved packets because of this for the case where
STAs send PS-Poll frames with PwrMgmt flag set.
This patch modifies the power save code to use the same struct
hostap_skb_tx_data as rest of the TX path in order to avoid corrupting
the data in skb->cb.
In addition, this patch reorders fields in the structure and makes
them use smaller types in order to make the structure fit in skb->cb
on 64-bit hosts.

Hi,
This is a patch to incorporate comments from earlier 12 patches.
It also fixes a few issues we found during this time.
Following is a list of changes in this patch. Item 1 incorporates
earlier comments. Issues addressed in items 2 to 4 were discovered
recently.
1. wmb() call in s2io_xmit() replaced with mmiowb().
2. The dtx_control register was earlier programmed incorrectly
for Xframe II adapter.
3. As suggested by hardware team, after a reset, in case of
Xframe II adapter, we clear certain spurious errors by
clearing PCI-X ECC status register, "detected parity error"
bit in PCI_STATUS register and PCI_STATUS bit in txpic_int register.
4. On IBM PPC platforms, we found that in the Rx buffer replenish
function, two memory writes(one to the the descriptor length and
another to the ownership) were getting reordered. This was causing
the adapter to see the ownership transfered to it before the length
was updated.
One solution was to add a wmb() but since this would turnout expensive
on some platforms if called for every descriptor, we set the ownership
bit and other fields of '2' to 'N' Rx descriptors followed by a wmb()
and then set the ownership of first descriptor ('1').
Here the value 'N' is configurable by making it a module loadable
parameter (rxsync_frequency).
(NOTE: This parameter is a power of 2).
5. Bumped up the driver version no. to 2.0.2.1

Hi,
The last patch in this series fixes the following issues found during
testing.
1. Ensure we don't pass zero sized buffers to the card(which can lockup)
2. Restore the PCI-X parameters(in case of Xframe I adapter) after a reset.
3. Make sure total size of all FIFOs does not exceed 8192.

3. Remove EOI from reset during intialization.
4. Enable all 8 PCCs if Xframe II adapter.
5. Programs the RLDRAM size depending on the device.
(Note: RLDRAM size on XFARME-I is 64Mb whereas on XFRAME-II it's 32 Mb).
6. Enable extended(64-bit) statistics counters.
7. Program timer interrupt duration based on PCI/PCI-X clock speed.
8. Not required to save/restore PCI config space before/after reset.

Hi,
This patch relates to mostly performance related changes.
1. Fixed incorrect computation of PANIC level in rx_buffer_level().
2. Removed unnecessary PIOs(read/write of tx_traffic_int and
rx_traffic_int) from interrupt handler and removed read of
general_int_status register from xmit routine.
3. Enable two-buffer mode(for Rx path) automatically for SGI
systems. This improves Rx performance dramatically on
SGI systems.

Hi,
Below patch addresses few h/w specific issues.
1. Check for additional ownership bit on Rx path before
starting Rx processing.
2. Enable only 4 PCCs(Per Context Controller) for Xframe I
revisions less than 4.
3. Program Rx and Tx round robin registers depending on
no. of rings/FIFOs.
4. Tx continous interrupts is now a loadable parameter.
5. Reset the card if we get double-bit ECC errors.
6. A soft reset of XGXS being done to force a link state change has been
eliminated.
7. After a reset, clear "parity error detected" bit,
PCI-X ECC status register, and PCI_STATUS bit in
tx_pic_int register.
8. The error in the disabling allmulticast implementation has been
rectified.
9. Leave the PCI-X parameters MMRBC, OST etc. at their
BIOS/system defaults.
