Subject: net/bnx2x: fix link state
X-Git-Url: http://git.droids-corp.org/?a=commitdiff_plain;h=6c5b9b2aaf3945638af8acba00048b0454355d51;p=dpdk.git

net/bnx2x: fix link state

Don't call bnx2x_link_status_update() from bnx2x_link_update().
Actual use case of bnx2x_link_status_update() is to update the link
status in shared memory between driver and MFW, and not to get the
link status from HW.

So ideally, bnx2x_link_status_update() should be called when there
is an actual link event or change in link status.

Calling bnx2x_link_status_update() from bnx2x_link_update() may
corrupt the data of link status in shared memory and result
in inconsistent state of link.
