============================= |

|
|
autocorking_size - INTEGER |
|
Setting SMC auto corking size: |
|
SMC auto corking is like TCP auto corking from the application's |
|
perspective of view. When applications do consecutive small |
|
write()/sendmsg() system calls, we try to coalesce these small writes |
|
as much as possible, to lower total amount of CDC and RDMA Write been |
|
sent. |
|
autocorking_size limits the maximum corked bytes that can be sent to |
|
the under device in 1 single sending. If set to 0, the SMC auto corking |
|
is disabled. |
|
Applications can still use TCP_CORK for optimal behavior when they |
|
know how/when to uncork their sockets. |
|
|
|
Default: 64K |
|
|
|
smcr_buf_type - INTEGER |
|
Controls which type of sndbufs and RMBs to use in later newly created |
|
SMC-R link group. Only for SMC-R. |
|
|
|
Default: 0 (physically contiguous sndbufs and RMBs) |
|
|
|
Possible values: |
|
|
|
- 0 - Use physically contiguous buffers |
|
- 1 - Use virtually contiguous buffers |
|
- 2 - Mixed use of the two types. Try physically contiguous buffers first. |
|
If not available, use virtually contiguous buffers then.
