Hi,
While working on TSO based solution I faced the following two questions:
1.
is there a maximum pkt_len to be used with TSO?, e.g. let's say if seg_sz
is 1400 can the entire segmented pkt be 256K (higer than 64K) ?, then the
driver gets a list of chanined mbufs while the first mbuf is set to T

Hi Xie,
I've got warnings from checkpatch.pl.
Mostly 'over 80 characters' warnings.
(But I know these are come from original vhost-example code sometimes.)
So far, your patches are RFC, so I haven't check these strictly.

Enqueue and dequeue burst functions always return a positive
value (including 0), so return type should be unsigned,
instead of int.

Each pthread needs to have assigned some identifier same way as you are doing

Hi Konstantin,
Thanks for the reply.
I was trying to find more intuitive one compare to rte_mempool_obj_iter().
Once mempool is created with objects, shouldn't we able to walk-through by just
passing 'mp' object and avoiding other params like vaddr, elt_size etc. For
now, I could use callbac

FWIW, it surprised the heck out of me as well.
Turns out that even though I'm compiling in 64-bit mode, gcc has
sizeof(int) as 4 bytes rather than 8. Not really sure what the scoop is on
that, but the standard leaves that up to the compiler. I'm used to int
always being the "natural size" on the C
