There is a debugfs knob to configure the maximal length of the A-MSDU. If this value is not 0 (which is the default), allow Tx A-MSDU even if the rate control disallows it. While at it, add "unlikely" to the if that limits the length of the A-MSDU based on the debugfs hook.

Add a timer in order to release expired frames from the reorder buffer. This is needed since some APs do not retransmit frames to fill in the reorder holes and in TCP it results with a complete stall of traffic. This has a few side effects on the general design: The nssn may not reflect the the head of the reorder buffer. This situation is valid, and packets with SN lower than the reorder buffer head will be dropped. Another side effect is that since the reorder timer might expire we need to lock the reorder buffer. This however is fine since the locking is only inside a single reorder buffer between RX path and reorder timeout and there is no outside contention.

Next hardware will direct packets to core based on the TCP/UDP streams. This logic can create holes in reorder buffer since packets that belong to other stream were directed to a different core. However, those are valid holes and the packets can be indicated in L3 order. The hardware will utilize a mechanism of informing the driver of the normalized ssn and the driver shall release all packets that SN is lower than the nssn. This enables managing the reorder across the queues without sharing any data between them. The reorder buffer is allocated and released directly in the RX path in order to avoid various races between control path and rx path. The code utilizes the internal messaging to notify rx queues of when to delete the reorder buffer.

According to the spec when a BA session is started there is a timeout set for the session in the ADDBA request. If there is not activity on the TA/TID then the session expires and a DELBA is sent. In order to check for the timeout, data must be shared among the rx queues. Add a timer that runs as long as BA session is active for the station and stops aggregation session if needed. This patch also lays the infrastructure for the reordering buffer which will be enabled in the next patches.

mac80211 will call the driver whenever there is a race between RSS queues and control path that requires a processing of all pending frames in RSS queues. Implement that by utilizing the internal notification mechanism: queue a message to all queues. When the message is received on a queue it decrements the atomic counter. This guarantees that all pending frames in the RX queue were processed since the message is in order inside the queue.

The TSO code creates A-MSDUs from a single large send. Each A-MSDU is an skb and skb->len doesn't include the number of bytes which need to be added for the headers being added (subframe header, TCP header, IP header, SNAP, padding). To be able to set the right value in the Tx command, we put the number of bytes added by those headers in driver_data in iwl_mvm_tx_tso and use this value in iwl_mvm_set_tx_cmd. The problem by setting this value in driver_data is that it overrides the ieee80211_tx_info. The bug manifested itself when we send P2P related frames in CCK since the rate in ieee80211_tx_info is zero-ed. This of course is a violation of the P2P specification. To fix this, copy the original ieee80211_tx_info to the stack and pass it to the functions which need it. Assign the number of bytes added by the headers to the driver_data inside the skb itself.

The firwmare file can come with data that is relevant for paging. This data is availablet to the firmware upon request, but it stored in the host's memory. During the firmware init flow, the driver configures the firmware so that the firwmare knows where is the data. When paging is used, the variable paging_mem_size is the number of bytes that are available through paging. This variable is not zeror-ed if the driver fails to configure the paging in the firmware, but the memory is freed which is inconsistent. This inconsistency led to a NULL pointer dereference in the code that collects the debug data. Fix this by zero-ing the paging_mem_size variable and NULLify the relevant pointers, so that the code that collects the debug data will know that the paging data is not available.

verifier is using the following structure to track the state of registers: struct reg_state { enum bpf_reg_type type; union { int imm; struct bpf_map *map_ptr; }; }; and later on in states_equal() does memcmp(&old->regs[i], &cur->regs[i],..) to find equivalent states. Throughout the code of verifier there are assignements to 'imm' and 'map_ptr' fields and it's not obvious that most of the assignments into 'imm' don't need to clear extra 4 bytes (like mark_reg_unknown_value() does) to make sure that memcmp doesn't go over junk left from 'map_ptr' assignment.

Enables the use of multiple transmit and receive scrqs allowing the ibmvnic driver to take advantage of multiqueue functionality. To achieve this, the driver must implement the process of negotiating the maximum number of queues allowed by the server. Initially, the driver will attempt to login with the maximum number of tx and rx queues supported by the server. If the server fails to allocate the requested number of scrqs, it will return partial success in the login response. In this case, we must reinitiate the login process from the request capabilities stage and attempt to login requesting fewer scrqs.
