and in some of them, there's a comment saying that, but in

The Large-Send Task Offload Tx Descriptor (9.2.1 Transmit) has a
Large-Send MSS value where the driver specifies the MSS. See the
datasheet here:
http://realtek.info/pdf/rtl8139cp.pdf
The code ignores this value and uses a hardcoded MSS of 1500 bytes
instead. When the MTU is less than 1500 bytes the hardcoded value
results in IP fragmentation and poor performance.
Use the Large-Send MSS value to correctly size Large-Send packets.
Jason Wang <jasowang@redhat.com> noticed that the Large-Send MSS value
mask was incorrect so it is adjusted to match the datasheet and Linux
8139cp driver.

There are two Tx Descriptor formats called mode 0 and mode 1. The mode
is determined by the Large Send bit.
CP_TX_IPCS (bit 18) is defined in mode 1 but the code checks the bit
unconditionally. In mode 0 bit 18 is part of the Large Send MSS value.
Explicitly check the Large Send bit to distinguish Tx command modes.
This avoids bugs where modes are confused. Note that I didn't find any
actual bugs aside from needlessly computing the IP checksum when the
Large Send bit is enabled.

The device turns the Tx Descriptor into a Tx Status descriptor after
fully reading the descriptor. This involves clearing Tx Own (bit 31) to
indicate that the driver has ownership of the descriptor again as well
as several other bits.
The code keeps the first dword of the Tx Descriptor in the txdw0 local
variable. txdw0 is reused to build the first word of the Tx Status
descriptor. Later on the code uses txdw0 again, incorrectly assuming
that it still contains the first dword of the Tx Descriptor. The tx
offloading code misbehaves because it sees bogus bits in txdw0.
Use a separate local variable for Tx Status and preserve Tx Descriptor
in txdw0.

This is a mostly-mechanical conversion that creates a new flat
union 'Netdev' QAPI type that covers all the branches of the
former 'NetClientOptions' simple union, where the branches are
now listed in a new 'NetClientDriver' enum rather than generated
from the simple union. The existence of a flat union has no
change to the command line syntax accepted for new code, and
will make it possible for a future patch to switch the QMP
command to parse a boxed union for no change to valid QMP; but
it does have some ripple effect on the C code when dealing with
the new types.
While making the conversion, note that the 'NetLegacy' type
remains unchanged: it applies only to legacy command line options,
and will not be ported to QMP, so it should remain a wrapper
around a simple union; to avoid confusion, the type named
'NetClientOptions' is now gone, and we introduce 'NetLegacyOptions'
in its place. Then, in the C code, we convert from NetLegacy to
Netdev as soon as possible, so that the bulk of the net stack
only has to deal with one QAPI type, not two. Note that since
the old legacy code always rejected 'hubport', we can just omit
that branch from the new 'NetLegacyOptions' simple union.

Originally, timers were ticks based, and it made sense to
add ticks to current time to know when to trigger an alarm.
But since commit:
7447545 change all other clock references to use nanosecond resolution accessors
All timers use nanoseconds and we need to convert ticks to nanoseconds, by
doing something like:
y = muldiv64(x, get_ticks_per_sec(), PCI_FREQUENCY)
where x is the number of device ticks and y the number of system ticks.
y is used as nanoseconds in timer functions,
it works because 1 tick is 1 nanosecond.
(get_ticks_per_sec() is 10^9)
But as PCI frequency is 33 MHz, we can also do:
y = x * 30; /* 33 MHz PCI period is 30 ns */
Which is much more simple.
This implies a 33.333333 MHz PCI frequency,
but this is correct.

rtl8139_do_receive() tries to check for the overflow condition
by making sure that packet_size + 8 does not exceed the
available buffer space. The issue here is that RxBuffAddr,
used to calculate available buffer space, is aligned to a
a 4 byte boundry after every update. So it is possible that
every packet ends up being slightly padded when written
to the receive buffer. This padding is not taken into
account when checking for overflow and we may end up missing
the overflow condition can causing buffer overwrite.
This patch takes alignment into consideration when
checking for overflow condition.
