The iwl_trans_pcie_alloc() function doesn't pass up error codes
returned from functions it calls, swallowing them and returning NULL
in all failure cases. The caller checks if the return value is NULL
and returns -ENOMEM. This is not correct, because in certain cases
the failure was not due to an OOM situation.
To fix this, modify the iwl_trans_pcie_alloc() function to use
ERR_PTR() to return error codes and clean up the error handling code
a bit.

This is a first step for improving fairness between legacy and 802.11n
traffic, and it should also improve reliability of resets and channel
changes by keeping the hardware queue depth very short.
When an aggregation session is torn down, all packets in the retry queue
will be removed from the BAW and freed.
For all subframes that have not been transmitted yet, the A-MPDU flag
will be cleared, and a sequence number allocated. This ensures that the
next A-MPDU session will get the correct initial sequence number.
This happens both on aggregation session start and stop.

When a packet has been tracked as part of the BlockAck window and added

Coalesce filters are configured in firmware based on settings
received from cfg80211.
Packet type which is required by firmware is determined based on
provided patterns in a rule:
Unicast: if pattern '01' with offset 0 is found
Multicast: if pattern '33:33' or '01:00:5e' with offset 0 is found
Broadcast: if pattern 'ff:ff:ff:ff' with offset 0 is found
Some example coalesce configuration files:
1) Coalesce Rx data packets from 192.168.0.88
mac address of our device is 00:50:43:21:53:7A
Source IP address offset comes out as 52 after following
calculations:
32 bytes of HW 802.11 header + 8 bytes LLC +
12 bytes in IPV4 header till source IP address
Destination mac is at offset 6 in HW header.
delay=100
condition=1
patterns=01,6+00:50:43:22,10+53:7A,52+c0:a8:00:58
2) Coalesce all broadcast and multicast packets(Multiple packet
types are not allowed in a single rule. Hence created separate
rules)
delay=400
condition=1
patterns=33:33
delay=400
condition=1
patterns=ff:ff:ff:ff
