Subject: RDMA/ocrdma: Dispatch only port event when port state changes
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=d310a344e18c1d9a6a2ab11ef15f2954418c493d;p=GitHub%2Fmoto-9609%2Fandroid_kernel_motorola_exynos9610.git

RDMA/ocrdma: Dispatch only port event when port state changes

Dispatch only port event to IB stack when port state changes.
Don't explicitly modify qps to error. Let application listen to
port events on async event queue or let QP fail with retry-exceeded
completion error.
