Public bug reported:
* Introduction
DPLL pin was exposed in upstream and backed into Bluefield kernel. But since
there are some other value was not needed in Bluefield kernel, they are not in
current Bluefield kernel. This may cause the value of IFLA_DPLL_PIN value be
not same as upstream and break user application.
* Explain the bug(s)
IFLA_DPLL_PIN is defined in if_link.h as an enum element. The following
elements before IFLA_DPLL_PIN are not needed by Bluefield kernel.
IFLA_GRO_MAX_SIZE,
IFLA_TSO_MAX_SIZE,
IFLA_TSO_MAX_SEGS,
IFLA_ALLMULTI, /* Allmulti count: > 0 means acts ALLMULTI */
IFLA_DEVLINK_PORT,
IFLA_GSO_IPV4_MAX_SIZE,
IFLA_GRO_IPV4_MAX_SIZE,
These missing elements will cause the value of IFLA_DPLL_PIN to be 58 in
Bluefield kernel while it is 65 in upstream. This inconsistent value may break
userspace applications.

* Brief explanation of fixes
Becasue these missing elements are not needed in Bluefield kernel. A
possible fix is to set the IFLA_DPLL_PIN to 65.
