Subject: Limit maximum number of pending SA Queries
X-Git-Tag: hostap_2_10~1586

Limit maximum number of pending SA Queries

There is no point in starting a huge number of pending SA Queries, so
limit the number of pending queries to 1000 to have an explicit limit
for how large sa_query_count can grow.
