When logging in remotely using ssh, there's now a 10 second delay,
cfr. the "ssh -v" output below:
debug1: ssh_ecdsa_verify: signature correct
debug1: SSH2_MSG_NEWKEYS sent
debug1: expecting SSH2_MSG_NEWKEYS
debug1: SSH2_MSG_NEWKEYS received
debug1: Roaming not allowed by server
debug1: SSH2_MSG_SERVICE_REQUEST sent
debug1: SSH2_MSG_SERVICE_ACCEPT received
----- 10 s delay ---
debug1: Authentications that can continue: publickey,password
debug1: Next authentication method: publickey
Wireshark doesn't show anything suspicious, just that there's a 10 s gap
before I receive an "encrypted response packet" on the client.
Hardware is r8a7791/koelsch, using sh_eth.
I bisected this to

net: Save software checksum complete
In skb_checksum complete, if we need to compute the checksum for the
packet (via skb_checksum) save the result as CHECKSUM_COMPLETE.
Subsequent checksum verification can use this.
Also, added csum_complete_sw flag to distinguish between software and
hardware generated checksum complete, we should always be able to trust
the software computation.

Reverting this commit fixes the issue.
Anyone with a clue?
Thanks!
