tcp buffer size tunables for iscsi connections
comstar - iSCSI/FC/SAS target
From the original bug at Delphix.
The tcp buffer sizes used for the iscsi connections are hardcoded to 256K. The values are hardcoded in idm_so.h: #define IDM_RCVBUF_SIZE (256 * 1024) #define IDM_SNDBUF_SIZE (256 * 1024) These sizes are inadequate for high bandwidth(10g networks) and/or high latency networks.
The fix should leave the default values but allow them to be tuned through /etc/system via idm:idm_so_sndbuf / idm:idm_so_rcvbuf
