-Stopping the port does not down the link on Intel® 40G Ethernet controller
---------------------------------------------------------------------------
-
-**Description**:
-   On Intel® 40G Ethernet Controller stopping the port does not really down the port link.

-**Implication**:
-   The port link will be still up after stopping the port.

+DPDK may not build on some Intel CPUs using clang < 3.7.0
+---------------------------------------------------------
+
+**Description**:
+   When compiling DPDK with an earlier version than 3.7.0 of clang, CPU flags are not detected on some Intel platforms
+   such as Intel Broadwell/Skylake (and possibly future CPUs), and therefore compilation fails due to missing intrinsics.
+
+**Implication**:
+   DPDK will not build when using a clang version < 3.7.0.
+
+**Resolution/Workaround**:
+   Use clang 3.7.0 or higher, or gcc.
+
+**Affected Environment/Platform**:
+   Platforms with Intel Broadwell/Skylake using an old clang version.
+
+**Driver/Module**:
+   Environment Abstraction Layer (EAL).

+
+The last EAL argument is replaced by the program name in argv[]
+---------------------------------------------------------------
+
+**Description**:
+   The last EAL argument is replaced by program name in ``argv[]`` after ``eal_parse_args`` is called.
+   This is the intended behavior but it causes the pointer to the last EAL argument to be lost.
+
+**Implication**:
+  If the last EAL argument in ``argv[]`` is generated by a malloc function, changing it will cause memory
+  issues when freeing the argument.
+
+**Resolution/Workaround**:
+   An application should not consider the value in ``argv[]`` as unchanged.
+
+**Affected Environment/Platform**:
+   ALL.

+I40e VF may not receive packets in the promiscuous mode
+-------------------------------------------------------
+
+**Description**:
+   Promiscuous mode is not supported by the DPDK i40e VF driver when using the
+   i40e Linux kernel driver as host driver.
+
+**Implication**:
+   The i40e VF does not receive packets when the destination MAC address is unknown.
+
+**Resolution/Workaround**:
+   Use a explicit destination MAC address that matches the VF.

+**Affected Environment/Platform**:
+   All.
