Flows accessing registers require the flow to hold a PTT entry. To protect 'major' load/unload flows a main_ptt is pre-allocated to guarantee such flows wouldn't be blocked by PTT being unavailable. Status block initialization currently uses the main_ptt which is incorrect, as this flow might run concurrently to others [E.g., loading qedr while toggling qede]. That would have dire effects as it means registers' access to device breaks and further read/writes might access incorrect addresses. Instead, when initializing status blocks acquire/release a PTT as part of the flow. Signed-off-by: Yuval Mintz <Yuval.Mintz@cavium.com> Signed-off-by: David S. Miller <davem@davemloft.net>
