From: Don Hiatt Date: Fri, 4 Aug 2017 20:53:58 +0000 (-0700) Subject: IB/hfi1: Add support to receive 16B bypass packets X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=72c07e2b671eda1cf3e8ebabc664f542f673b997;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git IB/hfi1: Add support to receive 16B bypass packets We introduce a struct hfi1_16b_header to support 16B headers. 16B bypass packets are received by the driver and processed similar to 9B packets. Add basic support to handle 16B packets.
