**Description**:
The supported network interface cards can come in a number of variants with different device ID's.
- Not all of these variants have been tested with the Intel® DPDK.

-IEEE1588 support possibly not working with an Intel® Ethernet Controller I210 NIC
----------------------------------------------------------------------------------
-
-**Description**:
- IEEE1588 support is not working with an Intel® Ethernet Controller I210 NIC.
-
-**Implication**:
- IEEE1588 packets are not forwarded correctly by the Intel® Ethernet Controller I210 NIC.
-
-**Resolution/Workaround**:
- There is no workaround available.
-
-**Affected Environment/Platform**:
- All.

-**Driver/Module**:
- IGB Poll Mode Driver

-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.
-
-**Resolution/Workaround**:
- None

+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.
