The interrupt coalescing self-adaptive function updates the int_gl every

This patch changes the GL update rate to every one hundred interrupts.

When changing the mtu, the max frame size also will be changed. The tx
buffer size and the rx buffer size to be allocated are determined by max
frame size. So when max frame size is changed, the tx buffer and rx buffer
need to be reallocated.
When the tc_num is changed, the tx buffer and rx buffer need to be

In VLAN_AWARE mode CPSW can insert VLAN header encapsulation word on Host
port 0 egress (RX) before the packet data if RX_VLAN_ENCAP bit is set in
CPSW_CONTROL register. VLAN header encapsulation word has following format:
HDR_PKT_Priority bits 29-31 - Header Packet VLAN prio (Highest prio: 7)
HDR_PKT_CFI bits 28 - Header Packet VLAN CFI bit.
HDR_PKT_Vid bits 27-16 - Header Packet VLAN ID
PKT_Type bits 8-9 - Packet Type. Indicates whether the packet is
VLAN-tagged, priority-tagged, or non-tagged.
00: VLAN-tagged packet
01: Reserved
10: Priority-tagged packet
11: Non-tagged packet
This feature can be used to implement TX VLAN offload in case of
VLAN-tagged packets and to insert VLAN tag in case Non-tagged packet was
received on port with PVID set. As per documentation, CPSW never modifies
packet data on Host egress (RX) and as result, without this feature
enabled, Host port will not be able to receive properly packets which
entered switch non-tagged through external Port with PVID set (when
non-tagged packet forwarded from external Port with PVID set to another
external Port - packet will be VLAN tagged properly).
Implementation details:
- on RX driver will check CPDMA status bit RX_VLAN_ENCAP BIT(19) in CPPI
descriptor to identify when VLAN header encapsulation word is present.
- PKT_Type = 0x01 or 0x02 then ignore VLAN header encapsulation word and
pass packet as is;
- if HDR_PKT_Vid = 0 then ignore VLAN header encapsulation word and pass
packet as is;
- In dual mac mode traffic is separated between ports using default port
vlans, which are not be visible to Host and so should not be reported.
Hence, check for default port vlans in dual mac mode and ignore VLAN header
encapsulation word;
- otherwise fill SKB with VLAN info using __vlan_hwaccel_put_tag();
- PKT_Type = 0x00 (VLAN-tagged) then strip out VLAN header from SKB.

When we re-enable ATR we need to restore the input set for TCPv4
filters, in order for ATR to function correctly. We already do this for
the normal case of re-enabling ATR when disabling ntuple support.
However, when re-enabling ATR after the last TCPv4 filter is removed (but
when ntuple support is still active), we did not restore the TCPv4
filter input set.
This can cause problems if the TCPv4 filters from FDir had changed the
input set, as ATR will no longer behave as expected.
When clearing the ATR auto-disable flag, make sure we restore the TCPv4
input set to avoid this.
