Hi Ferruh,
Added recommended modifications and resubmitted the patch. Removed
offloads handling part and "DEV_TX_OFFLOAD_MULTI_SEGS" Flag also as it is not
yet supported by driver.
Commit 0625a29f42c62998318ee3e05b2420e436318678 forces the usage of
DEV_TX_OFFLOAD_MULTI_SEGS for using ptpclient test application. I had to remove
this commit for my test. Any inputs on how this can be handled ?
Regards
Selwin

For the patch title, "net/axgbe: " already says the change is in the 'axgbe'
driver, no need to duplicate " .. support for axgbe".

The coding convention [1] we have says return type will be on seperate line, as
already done in some of these functions. Since this is new code, better to
start good, can you please apply the coding convention to all fucntions, like:
static inline uint64_t
div_u64(uint64_t dividend, uint32_t divisor)

This change seems unrelated with the rest of the patch, and I far as I remember
this was in the another patch too. What do you think making this seperate patch
with the proper description it deserves?
