Andrew Boyer b671e69ae4 net/ionic: update MTU calculations
Test min and max MTU against values read from firmware, for correctness.
Update the firmware field name, for clarity.
The device must be stopped before changing MTU, for correctness.
Store the calculated frame size in the queue, for performance.

*
* IONIC_TXQ_DESC_OPCODE_CSUM_NONE:
* Non-offload send. No segmentation,
* fragmentation or checksum calc/insertion is
* performed by device; packet is prepared
* to send by software stack and requires
* no further manipulation from device.
*
* IONIC_TXQ_DESC_OPCODE_CSUM_PARTIAL:
* Offload 16-bit L4 checksum
* calculation/insertion. The device will
* calculate the L4 checksum value and
* insert the result in the packet's L4
* header checksum field. The L4 checksum
* is calculated starting at @csum_start bytes
* into the packet to the end of the packet.
* The checksum insertion position is given
* in @csum_offset, which is the offset from
* @csum_start to the checksum field in the L4
* header. This feature is only applicable to
* protocols such as TCP, UDP and ICMP where a
* standard (i.e. the 'IP-style' checksum)
* one's complement 16-bit checksum is used,
* using an IP pseudo-header to seed the
* calculation. Software will preload the L4
* checksum field with the IP pseudo-header
* checksum.
*
* For tunnel encapsulation, @csum_start and
* @csum_offset refer to the inner L4
* header. Supported tunnels encapsulations
* are: IPIP, GRE, and UDP. If the @encap
* is clear, no further processing by the
* device is required; software will
* calculate the outer header checksums. If
* the @encap is set, the device will
* offload the outer header checksums using
* LCO (local checksum offload) (see
* Documentation/networking/checksum-offloads.rst
* for more info).
*
* IONIC_TXQ_DESC_OPCODE_CSUM_HW:
* Offload 16-bit checksum computation to hardware.
* If @csum_l3 is set then the packet's L3 checksum is
* updated. Similarly, if @csum_l4 is set the L4
* checksum is updated. If @encap is set then encap header
* checksums are also updated.
*
* IONIC_TXQ_DESC_OPCODE_TSO:
* Device performs TCP segmentation offload
* (TSO). @hdr_len is the number of bytes
* to the end of TCP header (the offset to
* the TCP payload). @mss is the desired
* MSS, the TCP payload length for each
* segment. The device will calculate/
* insert IP (IPv4 only) and TCP checksums
* for each segment. In the first data
* buffer containing the header template,
* the driver will set IPv4 checksum to 0
* and preload TCP checksum with the IP
* pseudo header calculated with IP length = 0.
*
* Supported tunnel encapsulations are IPIP,
* layer-3 GRE, and UDP. @hdr_len includes
* both outer and inner headers. The driver
* will set IPv4 checksum to zero and
* preload TCP checksum with IP pseudo
* header on the inner header.
*
* TCP ECN offload is supported. The device
* will set CWR flag in the first segment if
* CWR is set in the template header, and
* clear CWR in remaining segments.
* @flags:
* vlan:
* Insert an L2 VLAN header using @vlan_tci
* encap:
* Calculate encap header checksum
* csum_l3:
* Compute L3 header checksum
* csum_l4:
* Compute L4 header checksum
* tso_sot:
* TSO start
* tso_eot:
* TSO end
* @num_sg_elems: Number of scatter-gather elements in SG
* descriptor
* @addr: First data buffer's DMA address
* (Subsequent data buffers are on txq_sg_desc)
* @len: First data buffer's length, in bytes
* @vlan_tci: VLAN tag to insert in the packet (if requested
* by @V-bit). Includes .1p and .1q tags
* @hdr_len: Length of packet headers, including
* encapsulating outer header, if applicable
* Valid for opcodes IONIC_TXQ_DESC_OPCODE_CALC_CSUM and
* IONIC_TXQ_DESC_OPCODE_TSO. Should be set to zero for
* all other modes. For
* IONIC_TXQ_DESC_OPCODE_CALC_CSUM, @hdr_len is length
* of headers up to inner-most L4 header. For
* IONIC_TXQ_DESC_OPCODE_TSO, @hdr_len is up to
* inner-most L4 payload, so inclusive of
* inner-most L4 header.
* @mss: Desired MSS value for TSO; only applicable for
* IONIC_TXQ_DESC_OPCODE_TSO
* @csum_start: Offset from packet to first byte checked in L4 checksum
* @csum_offset: Offset from csum_start to L4 checksum field

* and every interrupt assert results in an
* interrupt. Reset value: 0
* @mask: Interrupt mask. When @mask=1 the interrupt
* resource will not send an interrupt. When
* @mask=0 the interrupt resource will send an
* interrupt if an interrupt event is pending
* or on the next interrupt assertion event.
* Reset value: 1
* @int_credits: Interrupt credits. This register indicates
* how many interrupt events the hardware has
* sent. When written by software this
* register atomically decrements @int_credits
* by the value written. When @int_credits
* becomes 0 then the "pending interrupt" bit
* in the Interrupt Status register is cleared
* by the hardware and any pending but unsent
* interrupts are cleared.
* !!!IMPORTANT!!! This is a signed register.
* @flags: Interrupt control flags
* @unmask -- When this bit is written with a 1
* the interrupt resource will set mask=0.
* @coal_timer_reset -- When this
* bit is written with a 1 the
* @coalescing_curr will be reloaded with
* @coalescing_init to reset the coalescing
* timer.
* @mask_on_assert: Automatically mask on assertion. When
* @mask_on_assert=1 the interrupt resource
* will set @mask=1 whenever an interrupt is
* sent. When using interrupts in Legacy
* Interrupt mode the driver must select
* @mask_on_assert=0 for proper interrupt
* operation.
* @coalescing_curr: Coalescing timer current value, in
* microseconds. When this value reaches 0
* the interrupt resource is again eligible to
* send an interrupt. If an interrupt event
* is already pending when @coalescing_curr
* reaches 0 the pending interrupt will be
* sent, otherwise an interrupt will be sent
* on the next interrupt assertion event.
