From d8d8ccf277419b6feb281a2d08d9f881b2b724be Mon Sep 17 00:00:00 2001 From: Bert Kenward Date: Mon, 18 Dec 2017 16:57:18 +0000 Subject: [PATCH] sfc: update EF10 register definitions The RX_L4_CLASS field has shrunk from 3 bits to 2 bits. The upper bit was never used in previous hardware, so we can use the new definition throughout. The TSO OUTER_IPID field was previously spelt differently from the external definitions.
