From a28c257c9eb0bd76a4adcac97c07e34044ec71fb Mon Sep 17 00:00:00 2001 From: Sowmini Varadhan Date: Fri, 29 May 2015 17:28:07 -0400 Subject: [PATCH] net/rds: Declare SO_RDS_TRANSPORT and RDS_TRANS_* constants in uapi/linux/rds.h User space applications that desire to explicitly select the underlying transport for a PF_RDS socket may do so by using the SO_RDS_TRANSPORT socket option at the SOL_RDS level before bind(). The integer argument provided to the socket option would be one of the RDS_TRANS_* values, e.g., RDS_TRANS_TCP. This commit exports the constant values need by such applications via Signed-off-by: Sowmini Varadhan Signed-off-by: David S.
