2022-07-05cxgb4: Use the bitmap API to allocate bitmapsChristophe JAILLET1-5/+3
Use bitmap_zalloc()/bitmap_free() instead of hand-writing them. It is less verbose and it improves the semantic. While at it, remove a useless bitmap_zero(). The bitmap is already zeroed when allocated.

2021-06-14cxgb4: fix wrong ethtool n-tuple rule lookupRahul Lakkireddy1-8/+16
The TID returned during successful filter creation is relative to the region in which the filter is created. Using it directly always returns Hi Prio/Normal filter region's entry for the first couple of entries, even though the rule is actually inserted in Hash region. Fix by analyzing in which region the filter has been inserted and save the absolute TID to be used for lookup later.

2021-06-11cxgb4: halt chip before flashing PHY firmware imageRahul Lakkireddy1-3/+19
When using firmware-assisted PHY firmware image write to flash, halt the chip before beginning the flash write operation to allow the running firmware to store the image persistently. Otherwise, the running firmware will only store the PHY image in local on-chip RAM, which will be lost after next reset.

2021-06-11cxgb4: fix sleep in atomic when flashing PHY firmwareRahul Lakkireddy1-2/+0
Before writing new PHY firmware to on-chip memory, driver queries firmware for current running PHY firmware version, which can result in sleep waiting for reply.

2020-07-23cxgb4: add loopback ethtool self-testVishal Kulkarni1-0/+52
In this test, loopback pkt is created and sent on default queue. The packet goes until the Multi Port Switch (MPS) just before the MAC and based on the specified channel number, it either goes outside the wire on one of the physical ports or looped back to Rx path by MPS. In this case, we're specifying loopback channel, instead of physical ports, so the packet gets looped back to Rx path, instead of getting transmitted on the wire. v3: - Modify commit message to include test details. v2: - Add only loopback self-test.

We were returning DUPLEX_UNKNOWN in get_link_ksettings() when the link was down. Unfortunately, this causes a problem when "ethtool -s autoneg on" is issued for a link which is down because the ethtool code first reads the settings and then reapplies them with only the changes provided on the command line. Which results in us diving into set_link_ksettings() with DUPLEX_UNKNOWN which is not DUPLEX_FULL, so set_link_ksettings() throws an -EINVAL error. do not return DUPLEX_UNKNOWN to fix the issue.
