whether it needs to be retried.

};
int rxrpc_kernel_check_call(struct socket *sock, struct rxrpc_call *call,
enum rxrpc_call_completion *_compl,
u32 *_abort_code);
On return, -EINPROGRESS will be returned if the call is still ongoing; if
it is finished, *_compl will be set to indicate the manner of completion,
*_abort_code will be set to any abort code that occurred. 0 will be
returned on a successful completion, -ECONNABORTED will be returned if the
client failed due to a remote abort and anything else will return an
appropriate error code.
The caller should look at this information to decide if it's worth
retrying the call.
(*) Retry a client call.
int rxrpc_kernel_retry_call(struct socket *sock,
struct rxrpc_call *call,
struct sockaddr_rxrpc *srx,
struct key *key);
This attempts to partially reinitialise a call and submit it again while
reusing the original call's Tx queue to avoid the need to repackage and
re-encrypt the data to be sent. call indicates the call to retry, srx the
new address to send it to and key the encryption key to use for signing or
encrypting the packets.
For this to work, the first Tx data packet must still be in the transmit
queue, and currently this is only permitted for local and network errors
and the call must not have been aborted. Any partially constructed Tx
packet is left as is and can continue being filled afterwards.
It returns 0 if the call was requeued and an error otherwise.
(*) Get call RTT.

invalid SACK and DSACK
====================
When a SACK (or DSACK) block is invalid, a corresponding counter would
be updated. The validation method is base on the start/end sequence
number of the SACK block. For more details, please refer the comment
of the function tcp_is_sackblock_valid in the kernel source code. A
SACK option could have up to 4 blocks, they are checked
individually. E.g., if 3 blocks of a SACk is invalid, the
corresponding counter would be updated 3 times. The comment of the
`Add counters for discarded SACK blocks`_ patch has additional
explaination:
.. _Add counters for discarded SACK blocks: https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/?id=18f02545a9a16c9a89778b91a162ad16d510bb32
* TcpExtTCPSACKDiscard
This counter indicates how many SACK blocks are invalid. If the invalid
SACK block is caused by ACK recording, the TCP stack will only ignore
it and won't update this counter.
* TcpExtTCPDSACKIgnoredOld and TcpExtTCPDSACKIgnoredNoUndo
When a DSACK block is invalid, one of these two counters would be
updated. Which counter will be updated depends on the undo_marker flag
of the TCP socket. If the undo_marker is not set, the TCP stack isn't
likely to re-transmit any packets, and we still receive an invalid
DSACK block, the reason might be that the packet is duplicated in the
middle of the network. In such scenario, TcpExtTCPDSACKIgnoredNoUndo
will be updated. If the undo_marker is set, TcpExtTCPDSACKIgnoredOld
will be updated. As implied in its name, it might be an old packet.
SACK shift
=========
The linux networking stack stores data in sk_buff struct (skb for
short). If a SACK block acrosses multiple skb, the TCP stack will try
to re-arrange data in these skb. E.g. if a SACK block acknowledges seq
10 to 15, skb1 has seq 10 to 13, skb2 has seq 14 to 20. The seq 14 and
15 in skb2 would be moved to skb1. This operation is 'shift'. If a
SACK block acknowledges seq 10 to 20, skb1 has seq 10 to 13, skb2 has
seq 14 to 20. All data in skb2 will be moved to skb1, and skb2 will be
discard, this operation is 'merge'.
* TcpExtTCPSackShifted
A skb is shifted
* TcpExtTCPSackMerged
A skb is merged
* TcpExtTCPSackShiftFallback
A skb should be shifted or merged, but the TCP stack doesn't do it for
some reasons.

TCP receive window
=================
* TcpExtTCPWantZeroWindowAdv
Depending on current memory usage, the TCP stack tries to set receive
window to zero. But the receive window might still be a no-zero
value. For example, if the previous window size is 10, and the TCP
stack receives 3 bytes, the current window size would be 7 even if the
window size calculated by the memory usage is zero.
* TcpExtTCPToZeroWindowAdv
The TCP receive window is set to zero from a no-zero value.
* TcpExtTCPFromZeroWindowAdv
The TCP receive window is set to no-zero value from zero.
Delayed ACK
==========
The TCP Delayed ACK is a technique which is used for reducing the
packet count in the network. For more details, please refer the
`Delayed ACK wiki`_
.. _Delayed ACK wiki: https://en.wikipedia.org/wiki/TCP_delayed_acknowledgment
* TcpExtDelayedACKs
A delayed ACK timer expires. The TCP stack will send a pure ACK packet
and exit the delayed ACK mode.
* TcpExtDelayedACKLocked
A delayed ACK timer expires, but the TCP stack can't send an ACK
immediately due to the socket is locked by a userspace program. The
TCP stack will send a pure ACK later (after the userspace program
unlock the socket). When the TCP stack sends the pure ACK later, the
TCP stack will also update TcpExtDelayedACKs and exit the delayed ACK
mode.
* TcpExtDelayedACKLost
It will be updated when the TCP stack receives a packet which has been
ACKed. A Delayed ACK loss might cause this issue, but it would also be
triggered by other reasons, such as a packet is duplicated in the
network.
Tail Loss Probe (TLP)
===================
TLP is an algorithm which is used to detect TCP packet loss. For more
details, please refer the `TLP paper`_.
.. _TLP paper: https://tools.ietf.org/html/draft-dukkipati-tcpm-tcp-loss-probe-01
* TcpExtTCPLossProbes
A TLP probe packet is sent.
* TcpExtTCPLossProbeRecovery
A packet loss is detected and recovered by TLP.
