Using a u32 to store a single flag is overkill.
Use a bool to store whether the buffer is stale or not.

Almost all drivers do not support user_claim, so remove it

When TX aggregation becomes operational, we do a number of steps:
1) print a debug message
2) wake the virtual queue
3) notify the driver
Unfortunately, 1) and 3) are only done if the driver is first to
reply to the aggregation request, it is, however, possible that the
remote station replies before the driver! Thus, unify the code for
this and call the new function ieee80211_agg_tx_operational in both
places where TX aggregation can become operational.
Additionally, rename the driver notification from
IEEE80211_AMPDU_TX_RESUME to IEEE80211_AMPDU_TX_OPERATIONAL.

Remove the PCI retry timeout code as that was just taken from ipw2100
due to historical reasons but in reality its a no-op, additionally its
simply incorrect as each PCI devices has its own custom PCI configuration
space on PCI config space >= 0x40. Not to mention we were trying to write
0 to a place that already has 0 on it.

as we make more descriptors available we let the show continue
