From: David Howells Date: Thu, 8 Sep 2016 10:10:11 +0000 (+0100) Subject: rxrpc: Update protocol definitions slightly X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=18f1387c7d7c6827b3ed6adf6ae20f65a58dc7b0;p=GitHub%2FLineageOS%2Fandroid_kernel_motorola_exynos9610.git rxrpc: Update protocol definitions slightly Update the protocol definitions in include/rxrpc/packet.h slightly: (1) Get rid of RXRPC_PROCESS_MAXCALLS as it's redundant (same as RXRPC_MAXCALLS). (2) In struct rxrpc_jumbo_header, put _rsvd in a union with a field called cksum to match struct rxrpc_wire_header. (3) Provide RXRPC_JUMBO_SUBPKTLEN which is the total of the amount of data in a non-terminal subpacket plus the following secondary header for the next packet included in the jumbo packet.
